INTRODUCTION
Copper smelters are a significant source of airborne particulates. The
fugitive dust emissions from various stages of the process are collected by
hoods placed over equipment and ducting to control devices.
In conjunction with the Environmental Protection Agency's Program for
developing new source performance standards, TRW and Monsanto Research Cor-
poration performed fugitive emission tests at seven copper smelters including
the Asarco smelters at El Paso, Texas afnd Tacoma, Washington, the Phelps-
Dodge smelters at Ajo and Douglas, Arizona and Playas, New Mexico, the
Kennecott smelter at Magma, Utah and the Anaconda smelter at Butte, Montana.
The scope of this testing program, designed to provide data on arsenic
and sulfur dioxide emissions, has been extended to lead by laboratory analysis
on the samples collected.
The first two copper smelters tested in the program, the Anaconda plant at
Butte, Montana and the Asarco plant at El Paso, Texas, were sampled by Monsanto
Research Corporation. At Asarco, El Paso, Monsanto tested the fugitive
emissions collected by hoods placed over the converter line at points before
and after the emissions entered the sulfuric acid plant. Also tested by
Monsanto were the fugitive emissions collected in the roaster building at
points before the emissions enter an electrostatic precipitator, and at a
point in the ballon flue on the outlet of the electrostatic precipitator.
In January of 1978 TRW sampled at the Asarco smelter in El Paso. Sites
tested by TRW included the converter building fugitive emissions baghouse,
the calcining and matte tapping fugitive emissions ducts.
The Phelps-Dodge copper smelters at Douglas and Ajo, Arizona and Playas,
New Mexico were sampled by TRW in May, June and July 1978 respectively.
At the Douglas, Arizona plant, TRW sampled the calcine/roaster baghouse,
which collected fugitive emissions during the loading process of the train
car. The train car transported the concentrate to the reverberatory furnace
operation. The fugitive emission system operated on an intermittant basis.
At the Phelps-Dodge Ajo smelter, TRW sampled the fugitive emission^
systems of the converter slag and copper blow cycle, and the matte tapping
operation from the reverberatory furnace. The sulfuric acid plant attached
to the copper smelter was also sampled at the inlet to the electrostatic
precipitator. the electrostatic precipitator outlet/acid plant inlet, and the
acid plant outlet. The acid plant converts sulfur dioxide to sulfuric acid
with a contact catalyst.

-------
The converter slag and copper blow cycles were tested by TRW at the Phelps
Dodge Playas, New Mexico copper smelter.
In September 1978 and May 1979, TRW tested the Asarco copper smelter in
Tacoma, Washington, which processes ores high in arsenic. The TRW team per-
formed emission testing at the inlet and outlet of the roaster baghouse, the
inlet and outlet of the arsenic kitchen, the inlet and outlet of the rever-
beratory furnace electrostatic precipitator, the fugitive emission systems of
the matte tapping, slag tapping, converter slag return, calcine, as well as the
converter during copper blow and full cycles and fugitive emissions not
controlled by the hoods over the converter.
TRW tested the Kennecott copper smelter at Magma, Utah in November 1978.
The matte tapping fugitive emission syst emotes ted was operated interim'ttantly
to control emissions from loading of coppe? matte from reactors to large
ladles. The slag tapping futivive emission system works similarly during
loading of slag from reactors to the layer ladles. Also tested by TRW were
the converter fugitive emission system, the acid plant inlet and the concen-
trate dryer emission system which removes water and fugitive dust from the
rotating concentrate dryers.
This report presents the results of laboratory analysis for lead on the
samples collected during this test program. Data is not complete for
some tests since some sample solutions required complete consumption in order
to accomplish the analysis for arsenic for the original test program.
-------
SUMMARY AND DISCUSSION OF RESULTS
ASARCO - El Paso, Texas; TRW Test program
The results of the emission testing at the five test locations are
summarized in Tables 1 - 4 of this report. Three sets of tests were per-
formed at the inlet and outlet of the converter building fugitive emissions
baghouse, the calcining fugitive emissions duct, and the matte tapping
fugitive duct. ^
In addition, analyses were performed on composited process samples
taken by plant personnel on the days that the fugitive emission testing was
being performed. This data is summarized in Table 44.
Since some of the samples from the converter baghouse outlet were
consumed in the previous analysis for arsenic the efficiency of the bag-
house for lead removal can not be determined. The converter baghouse inlet
averaged 6 Kg/hr of lead. Fugitive lead emissions from the calcining and
matte tapping operations averaged 0.4 Kg/hr and 0.5 Kg/hr respectively.

ASARCO - El Paso, Texas; Monsanto test program
This program was separated into essentially two phases. The first phase
was sampling of the effluent of the converter line. These gases are collected
into ducts and directed to an induced draft fan. The exhaust of this fan is
directed .through a short section of duct work into a long spray chamber.
This short section of duct work is sampling location D, inlet to the sulfuric
acid plant. The gases leave the spray chamber and go to an electrostatic
precipitation particulate collection device.
From here they are directed to the inlet of the sulfuric acid plant. The
outlet of the sulfuric acid plant is an atmospherically vented stack. This
outlet duct is sampling location E. The second phase of this program was to
sample the outlets of the reverberatery furnace, the outlets of the multi-
hearth roasters, and the combination of these gases after passing through
the particulate removal system at the base of the main stack. The gases
from .the multi-hearth roasters are directed to a large downtake at the side
of the roaster building and down into a large existing brick flue. This
downtake is sampling location C. The gases from the reverberatory furnace
pass through two waste heat boilers and then through two rectangular ducts
into the same existing flue. These two flues are designated sampling
locations North B and South B. The gases in this flue pass to a spray
chamber, leave the spray chamber and pass through an electrostatic precipita-
tor. The gases leaving this electrostatic precipitator pass through a large
balloon flue and into the base of the main stack. This balloon flue is
sampling location A.
The lead concentration of fugitive emissions from the converter line,
which is summarized in Table 9, averages 2 Kg/hr.

Phelps-Dodge - Douglas, Arizona; TRW Test Program
Two main problems were encountered in the testing program at the Phelps-
Dodge copper smelter. When the TRW personnel arrived at the site, the plant
was not operating due to mechanical malfunction. This problem caused a one
and a half day delay in the testing program.
The second problem was the intermittent process operation. The emissions
being measured were during the loading of train cars that transported the
calcine. The loading operation took two to five minutes and the process
occurred once every twenty-five to thirty minutes. The testing necessitated
one traverse point per loading operation due to the variability in loading
times. Stop watches were utilized to obtain accurate times. All data was
time weighted to achieve the averages. This was accomplished to account for
variability in loading times.
The previous arsenic analysis on the samples collected required the
complete use of some fractions. This precludes calculation of total lead
concentrations. Results are summarized in Table 11 and 12.
During the data reduction, the meter volume was back calculated to account
for sulfur dioxide that was removed by the impingers containing 10% hydrogen
peroxide. The back calculation for sulfur dioxide was accomplished in the
following order. First parts per million sulfur dioxide at standard condi-
tions was calculated, then parts per million was converted to a fraction by
dividing by 106. This number was added to one and the result multiplied by
volume of gas collected through the dry meter at standard conditions. The
result of multiplication yielded the actual gas volume collected at atandard
conditions. Since SOg removal by the peroxide impingers does not reach the
dry gas meter, corrected values for dry gas meter volumes (at meter condi-
tions) found on the summary sheets will be slightly higher than those ob-
tained from the field data sheets.

Phelps-Dodge - Ajo, Arizona; TRW Test Program
During the program one additional test was run at the converter fugitive
emission system. The test was performed because of a possible error in rinsing
a U connector which was believed rinsed with acetone instead of .IN NaOH. To
compare results, the test, (Table 14) was included with other tests.
The sampling required coordination with plant officials to assure that
the testing was performed during the process operation.
The testing at the matte tapping fugitive emission system required inter-
mittent testing only when the copper matte was removed from the Reverb furnace.
The sampling at the converter fugitive^emission system required testing only
during the slag and copper blow cycles.
Due to high ambient temperature (116°F) and high sulfur dioxide concen-
tration at the acid plant testing locations, sampling was performed under
adverse conditions.
Test no. 2 at the north acid plant inlet was aborted because TRW
personnel inadvertently pointed the nozzle downstream. Because of the
ensuing mechanical problems at the plant, the TRW crew could not repeat
test no. 2. Results of the acid plant tests are summarized in Tables
15 - 18.
The fugitive lead emission from the converter averaged 0.24 Kg/hr,
and from the matte tapping, 0.11 Kg/hr (see Table 13). Because some samples
were consumed in the previous arsenic analysis the lead concentrations can
not be calculated.
During the data reduction, the meter volume was back calculated to
account for sulfur dioxide that was removed by the three 10% hydrogen
peroxide impingers. The back calculation for sulfur dioxide was accom-
plished in the following order. First, parts per million sulfur dioxide
at standard conditions was calculated. Then parts per million was con*.
verted to a fraction by dividing by 10°. This number was added to one
and the result multiplied by volume of gas collected through the dry gas
meter at standard conditions. The result of multiplication yielded the
actual gas volume collected at standard conditions. Since S02 removed
by the peroxide impingers does not reach the dry gas meter corrected values
for dry gas meter volume (at meter conditions) found on the summary sheets
will be slightly higher than those obtained from the field data sheets.

Phelps-Dodge - Playas, New Mexico; TRW Test Program
The process tested was a converter hooding system which removed fugi-
tive emissions from the converter during the copper blow cycle.
The testing consisted of three arsenic/sulfur dioxide tests and three
particle sizing tests which were performed during the copper blow cycles.
The testing location was a seven foot duct located between the hooding sys-
tem and the stack. These tests were coordinated with a process engineer
from the Environmental Protection Agency.
During the testing program the following observations and problems
were noted.
For the first test, twenty-five minutes per sampling point were used
to assure that sampling was done through a complete production cycle. For
the second and the third test, twenty minutes per sampling point and a
smaller nozzle size was utilized. After 155 minutes of the third test,
TRW personnel noticed that the AP readings were abnormally low. After
checking equipment, the process engineer discovered that the plant opera-
tors inadvertently left the dampers on the system in the open position. When
the problem was corrected, the AP reading increased to the appropriate reading.
Thus, during 80 minutes of the sampling period of the third test, dilution
air entered the duct which resulted in a non-respresentative sample.
Because of the previous arsenic analysis some sample fractions were
consumed, precluding the calculation of lead emission rates. Results are
summarized in Table 19.
During the Data Reduction, the meter volume was back calculated to
account for sulfur dioxide that was removed by the three 10% hydrogen
peroxide impingers. The back calculation for sulfur dioxide was accom-
plished in the following order. First, parts per million sulfur dioxide
at standard consitions were calculated. Then parts per million were converted
to a fraction by dividing by 10°. This number was added to one and the
result multiplied by the volume of gas collected through the dry gas
meter at standard conditions. The result of multiplication yielded the true
gas volume collected at standard conditions. Since S02 removal by the peroxide
impingers does not reach the dry gas meter, corrected values for dry gas meter
volumes (at meter conditions) found on the summary sheets will be slightly
higher than those obtained from the field data sheets.

ASARCO - Tacoma, Washington; TRW Test Program
Tables 20.and 21 give the results of the inlet and outlet tests at the
roaster baghouse. The inlet and outlet tests were done simultaneously during
normal operating periods of the roaster. The only difficulty encountered
during these test was the plugging of the inlet location nozzle several
times during these runs. The material plugging the nozzle was recovered
into the probe rinse container and the test was continued.
Table 22 presents the results of the tests done at the outlet from the
reverberatory furnace electrostatic precipitator. This location required
vertical sampling with a 15 foot probe and a teflon flex line between the
probe and the filter (see diagram #2). The duct had a significant amount of
sediment in the bottom which precluded sampling at several traverse points.
Since the plant was on curtailed production due to meteorological conditions
some delay was encountered in completing these tests.
The data from tests done at the matte tapping, slag tapping, calcine
discharge, and converter slag return are given in Tables 23, 24, 25 and 29,
respectively. The activities feeding these fugitive systems occur for short
periods throughout the converter cycle, and consequently sampling had to be
timed to coincide with this intermittant schedule. Matte and slag tapping
fugitive emissions were sampled over 5 to 8 minute periods when matte or slag
were being drawn from the reverberatory furnace. Sampling was coordinated
by EPA observers at the matte tapping and slag tapping areas who alerted the
sampling teams by transceiver as to when to start and stop sampling.
The emissions from the converter slag return were sampled during 1 to 3
minute intervals when slag was returned to the reverberatory furnace from
the converters. This procedure only occurred five to six times per day, so
that three days of testing were required to collect a large enough sample for
analysis.
Results of the tests on the arsenic baghouse are summarized in Tables 26,
27 and 28.
Data collected from tests done on the converter fugitive emissions
collected by hooding during the copper blow and full cycles are summarized
in Tables 30 and 31. Fugitive emissions not collected by the hooding system
were also sampled using anemometer to continuously record flow past the
sampling point. Results of these tests are summarized in Tables 32, 33 and
34.

Kennecott - Magma, Utah; TRW Test Program
The field sampling program encountered the following minor problems
which are outlined below with respect to the individual sampling locations.
During the field sampling at the matte tapping fugitive emission system
and the slag tapping fugitive emission system, the sampling program required
long days due to the intermittent process operation and days of reduced op-
eration. At the slag tapping fugitive emission duct there were two modifi-
cations in the sampling procedure required. Only one port was located on
the duct which required that both traverses be performed through the same
port utilizing the pythagoream calculations. The sampling train was modified
to allow for the two traverses through the single sampling port. A teflon
flex line was inserted between the probe and heater box to assist in maneu-
vering the probe into the proper placement. After the testing the flex line
was cleaned with a probe brush and .IN NaOH. The solution was placed in the
probe rinse bottle and saved for analysis.
Testing the converter fugitive emission system and the acid plant inlet
required TRW personnel to adjust the working schedule to fit the cyclic pro-
cess operation of the converter unit. Due to lack of space at the converter
fugitive emission duct sampling position, TRW was required to utilize the
flex lines between the probes and heater boxes on each of the tests. After
each test the flex line was cleaned with .IN NaOH and a probe brush. The
solution was placed in the probe rinse bottle and saved for analysis.
Weather forced TRW personnel to curtail the field sampling on Friday,
November 10, 1978. TRW personnel returned on Monday, November 12, 1978 to
complete the field sampling on the concentrate dryer fugitive emission system.
Testing the concentrate dryer fugitive emission system required the
test ports to be placed in the fiberglass stack. Due to the working space
and the fiberglass stack, TRW utilized the flex line inserted between the
probe and the heater box to assist in performing the sampling traverses.
Testing at the concentrate dryer fugitive emission system was performed under
low ambient temperature which ranged from 20°F to 30°F.
The average lead emission rate of the concentrate dryer fugitive emission
system (Table 40) was 0.1 Kg/hr. The fugitive emissions of lead from the
matte tapping and slag tapping, summarized in Tables 35 and 36, averaged
0.7 Kg/hr and 0.04 Kg/hr, respectively. Fugitive lead emissions from the
full cycle converter and rollout converter cycle both averaged about 0.4
Kg/hr and are summarized in Tables 38 and 39. The acid plant inlet (see
Table 37) had a lead concentration of 2.5 Kg/hr.
During the data reduction, the meter volume was back calculated to ac-
count for sulfur dioxide that was removed by the three 10% hydrogen peroxide
impingers. The back calculation for sulfur dioxide was accomplished in the
following order. First, parts per million sulfur dioxide at standard con-
ditions was calculated. Then parts per million was converted to a fraction
by dividing by 106. This number was added to one and the result multiplied
by volume of gas collected through dry gas meter at standard conditions.
The result of multiplication yielded the actual gas volume at standard
conditions collected.

LOCATION OF SAMPLING POINTS
Asarco - El Paso, Texas; TRW test program
1) Inlet to the Converter Building Fugitive Emissions Baghouse
Samples from the inlet to the converter building fugitive baghouse were
taken from a 152" diameter horizontal duct which is 50 feet above the
ground. Sampling ports on the top and side of the duct allowed for
vertical and horizontal traverses of the duct during sampling. The
nearest upstream flow disturbance was a bend 90 feet (7 diameters) away
from the sampling point. The nearest downstream disturbance was a bend
100 feet (8 diameters) downstream. Forty traverse points were chosen
so that the sampling period would coincide with that at the outlet from
the baghouse. Figure 1 is a diagram of the sampling location.
2) Outlet from the Converter Building Fugitive Emissions Baghouse
Samples from the outlet of the converter building fugitive baghouse
were taken from a 20' by 9' rectangular duct. The duct was horizontal
and the sampling point was 35 feet above the ground. The nearest up-
stream flow disturbance was 45 feet (3.5 equivalent diameters) away.
The nearest downstream disturbance was 12.5 feet (1 equivalent duct
diameter) away. Ten traverse points were selected at each of the four
sampling ports. Figure 2 is a diagram of this location.
3) Roaster Calcining Fugitive Emissions Duct
The roaster calcining fugitive emissions were sampled from a 28.5 inch
diameter circular duct which was 15 feet above the ground and at a 10
degree angle to the horizontal. The nearest upstream flow disturbance
was 75 feet away (32 diameters); the nearest downstream disturbance was
8 feet away (3.5 diameters). Twenty traverse points were selected for
sampling, ten on each of the two traverses. Figure 3 is a diagram of
this sampling location.
4) Outlet from the Roaster/Reverberatory Furnace Electrostatic Precipitator
The duct exiting the roaster/reverberatory furnace electrostatic precipi-
tator is a ballon shaped duct twenty-two feet high and twelve feet wide
at the top. The nearest upstream disturbance was 50 feet (4 diameters)
away; the nearest downstream disturbance was 20 feet (1.5 diameters)

away. Sampling was done at 50 traverse points. Figure 4 is the plan
view diagram of this sampling location. Figure 5 illustrates the cross-
sectioned view.
5) Matte Tapping Reverbatory Furnace Outlet
The fugitive emissions from the matte tapping reverbatory furnace were
sampled from a 32.75" diameter horizontal round duct. The nearest up-
stream disturbance was 20 feet (6 diameters) away; the nearest down-
stream disturbance was 12 feet (4 diameters) away. Sampling was done
at 24 traverse points on two traverses. Figure 6 is a diagram of this
sampling location.

There are two distinct control systems in the copper smelting facility.
The first controls the effluent from the converter line, and the second
controls the effluent from the multi-hearth roasters and the reyerberatory
furnace. The effluent of the converter line passes through an induced draft
fans a spray chamber, an electrostatic precipitator, and finally through
a sulfuric acid plant. The gases from the multi-hearth roasters are joined
by the gases from the reverberatory furnace, pass through a spray chamber,
are then cleaned in an electrostatic precipitator, and then are directed to
the base of the main stack where they are emitted to the atmosphere. The
first system we will discuss is the effluent of the converter line.
EFFLUENT OF THE CONVERTER LINE
Point D Effluent of Converters
Gases are collected from the converters in a system of duct work and
directed out of the building, in two ducts, to the plenum chamber inlet
of an induced draft (I.D.) fan. The outlet of this fan is sampling point
D. The gases leave the fan through a transition duct and into an expansion
joint approximately 4-foot (1.22 m) long. The gas then passes through a
horizontal duct that is 75 inches (190.5 cm) inside diameter and 16 ft.
(4.88 m) long and into the inlet of the spray chamber. This section of
line, including the expansion joint, constituted a 20 foot (6.10 m) straight
length of duct work and was selected as site D, inlet to the converter line
control device.
Two 4 inch (10.2 cm) diameter pipe ports were located 4 foot (1.22 m)
from the spray chamber and 16 ft. (4.88 m) from the outlet of the fan,
giving 0.64 diameters downstream and 2.56 diameters upstream from the ports.
the ports were located on the top and side of the horizontal duct 90° apart.
A 44 point total traverse was required, however, the first and last points
on each 22 point traverse were less than 1 inch (2.54 cm) from the duct wall.
A 48 point total traverse was used and the first and last points were dropped
from each 24 point single traverse.
It was discovered on the initial velocity traverse that the bottom of
the duct had an accumulation of material in it. Only the first 13 points of
the vertical traverse were used to sample the duct. All 22 points of the
horizontal traverse were used. A sketch of this location is shown in Figure
70
Point E
Sampling point E is the outlet of the sulfuric acid plant. It is a
vertical stack with an atmospheric outlet. There is a straight section of
stack from the last disturbance (a tee section) to the outlet of about 35
to 40 ft. (10.67 to 12.19 m) and the inside diameter of the stack is 66
inches (167.6 cm). The ports were located approximately 12 feet (3.66 m)
from the disturbance to the ports and 4 or 5 diameters from the ports to the
79

outlet. The ports were 4 inch (10.16 cm) flanged pipe and were located 90°
from each other on the circumference of the stack. A 48 point total tra-
verse was laid out, however, the first and last points of each single tra-
verse were nearer than 1 inch (2.54 cm) from the stack wall and were not
used. A 44 point total traverse was used.
EFFLUENT OF THE ROASTER AND REVERBERATORY FURNACES
Point C - Effluent of the Roasters
Sampling point C is the effluent of the multi-hearth roasters. The out-
lets of the roasters are accumulated in a system of duct work and directed
to a large rectangular downtake flue at the top of the roaster building.
This downtake, constructed of brick, runs diagonally down the side of the
roaster building at approximately a 45° angle and joins the horizontal flue
that takes the gases to the cleaning system. This downtake is sampling
point C. Four 4 inch (10.16 cm) pipe sampling ports were installed in a
horizontal line across the downtake at the second level of the building on
both the inside and outside of the duct and scaffolding was erected on the
outside for access. Since the duct was approximately 14.5 feet (4.42 m)
square inside, the ports were in the range of 2.21 to 2.75 equivalent
diameters from the nearest upstream disturbance and 0.55 to 2.07 equivalent
diameters from the nearest downstream disturbance. A 40 point total
traverse was laid out to sample this duct. This would have consisted of 5
traverse points per port. The ports on both the inside and outside of the
duct nearest the bottom was found to be under an accumulation of dust and
therefore were not sampled. This left a 30 point traverse. A sketch of
this location is shown in Figure 8.
Point B - Effluent of the Reverberatory Furnaces
The gases leaving the reverberatory furnace first pass through a waste
heat recovery boiler and then through two I.D. fans. The outlet of these
fans are sampling point B. The two rectangular ducts from the fans,
designated South (SB) and North (NB), are 26 feet (7.92 m) long, 8 feet
(2.44 m) tall and 6 feet (1.83 m) wide giving an equivalent diameter of
6.857 feet (2.09 m). The ducts are about 12'feet (3.66 m) apart and both
empty into the long horizontal flue that already contains the gases from the
roaster process. Six 4 inch (10.16 cm) pipe ports were located on each of
the ducts on the 8 foot (2.44 m) wall facing each other and were offset 1
foot (.30 m) from each other along the length to facilitate probe handling
during simultaneous sampling. The South duct ports were located 15.5 ft.
(4.72 m) from the fan outlet and 10.5 ft. (3.20 m) from the flue giving
2.26 diameters upstream and 1.53 diameters downstream of unobstructed duct.
The North duct ports were located 14.5 ft. (4.42 m) from the fan and 11.5 ft.
(3.51 m) from the flue giving 2.11 diameters upstream and 1.68 diameters
downstream of unobstructed duct. Each port was sampled using 4 traverse
point locations so that a 24 point overall traverse was obtained on each
duct. A sketch of this location is shown in Figure 9.

POINT A - OUTLET OF THE ESP
Sampling point A is a large balloon flue that connects the ESP to the
base of the main stack. The flue exits the ESP building and turns right
about 30°. It then runs for a straight length of about 68 ft. (20.73 m)
where another bend occurs. From this point it continues to the main stack.
The sampling points are located approximately 48 ft. (14.63 m) from the
first bend and approximately 20 ft. from the second.
There are no guidelines for calculating an equivalent diameter for a
balloon shaped flue. The cross section of the flue has a semicircular top
of 6 ft. (1.83 m) radius, below this is a rectangular section 12 ft. (3.66
m) wide by 7.66 ft. (2.33 m) tall, and the bottom is a V shaped triangle
with a 12 ft. (3.66 m) top and a depth of about 9 ft. (2.74 m). This gives
a total area of approximately 200 ft2 (18.58 m2). An equivalent circular
duct would have a diameter of about 16 ft. (4.88 m). Using 16 ft. (4.88 m)
as an equivalent diameter the ports are located 3 diameters from the near-
est upstream bend and 1.25 diameters from the nearest downstream bend. This
would normally require about 40 points to traverse. Five 3 inch (7.62 cm)
ports were located on the top of the duct and were located on the top of the
top of the duct and were designated A through E across the duct. Due to the
shape of the duct, various numbers of points were used on each port.
Ports A and E were sampled using 7 points each, ports B and D with 11
points each and port C with 15 points. This gave a total traverse of 51
points. At each of the topmost points of each port traverse, no flow was
detected so the second point of each traverse was sampled twice as long.
This left a 46 point total traverse with the 5 uppermost points being
sampled at double the time of the others. A sketch of this location is
shown in Figure 10.

1) Roaster baghouse inlet - The duct carrying emissions from the roasting
process is balloon shaped, measuring 11 feet high and 8 feet wide at the
widest point. Sampling was done through four 4 inch sampling ports on
top of the flue. The nearest upstream disturbance was 50 feet (4 dia-
meters) away, the nearest downstream disturbance was a transition section
into the baghouse which was 10 feet away. Sampling was done at 20 tra-
verse points. Figure 22 is a diagram of the sampling location.
2) Roaster baghouse outlet - The treated gas leaving the roaster baghouse
was sampled approximately 1000 feet downstream from the baghouse. The
discharge duct was round, had an inside diameter of 90 inches, and had
sampling ports on the side and top. The nearest upstream disturbance
was 100 feet (13 diameters) and the nearest downstream disturbance was
40 feet (4 1/2 diameters) away. Sampling was done at 12 traverse points.
Figure 23 is a diagram of this sampling location.
3) Reverberatory furnace electrostatic precipitator - The outlet of the
electrostatic precipitator treating the emissions from the reverberatory
furnace has approximately 75 feet of straight ducting before entering
the main stack. There were ten sampling ports on the top of the rec-
tangular brick flue, which were 20 feet from the transition section
leaving the electrostatic precipitator. Forty-eight traverse points
were chosen for sampling, but it was found that a significant amount of
sediment in the duct precluded sampling at twelve of them. Figure 24
is a diagram of this location.
4) Matte tapping - Matte tapping emissions are captured by a moveable hood
over the matte tapping ladle and are ducted to the brick flue which goes
to the main stack after passing through an electrostatic precipitator.
These emissions were sampled in a vertical section of the round duct
approximately 100 feet above the hood. The nearest upstream disturbance
was 75 feet (22 diameters) away and the nearest downstream disturbance
was 10 feet (3 diameters) away. Samples were taken at eight traverse
points during matte tapping operations. Figure 25 is a diagram of this
sampling location.
5) Slag tapping - Slag tapping emissions are captured by a hood over the
slag trough and are ducted to the same brick flue as are the matte
tapping emissions. The emissions were sampled in a section which angles
down 20° from the horizontal. The sampling ports are twenty feet down-
stream from a 20° bend (5 diameters), and seven feet upstream from a 60°
bend (2 1/2 diameters). Samples were taken at twelve traverse points
during slag tapping operations. Figure 26 is a diagram of this location,,
6) Calcine discharge - Dust emissions from loaging lorry cars from the
roasters are collected from slots in the loading apparatus. These
emissions in turn are routed to the main brick flue through a 10 inch
duct. The emissions were sampled 9 feet (11 diameters) downstream from
the blower, which was the nearest upstream disturbance. Samples were

taken at a single point due to the small duct diameter. Sampling was
done only while lorry cars were being loaded. Figure 27 is a diagram
of this location.
7) Arsenic kitchen - Arsenic trioxide is produced in the arsenic kitchen
area. The effluent gases from this process are routed through a bag-
house before being discharged through the main stack. The sampling
location was at a vertical round duct which is 26 1/2 inches in diameter.
The nearest upstream disturbance was the transition from the arsenic
kitchen, a reducing section of ducting, which was 6 feet (3 diameters)
away. The nearest downstream disturbance was a 90° bend 5 feet (2 dia-
meters) away. Sampling was done at 24 traverse points. Figure 28 is
a diagram of this location.
8) Metallic arsenic - In the metallic arsenic area, arsenic trioxide is
converted to elemental arsenic. The effluent gases from this process
are routed to the same baghouse as are the arsenic kitchen discharges'.
The sampling location for this emission stream was in a 37.25 inch round
duct which slanted up at a 20° angle from the horizontal. The nearest
upstream flow disturbance was 50 feet (16 diameters) away, and the near-
est downstream flow disturbance was 6 feet (2 diameters) away. Sampling
was done at twelve traverse points. Figure 29 is a diagram of this
location.
9) Arsenic baghouse outlet - The discharge gases from the arsenic kitchen
baghouse were sampled approximately 500 feet downstream from the bag-
house. Samples were taken from a round horizontal duct with an inside
diameter of 37.75 inches. The nearest upstream flow disturbance was 75
feet (24 diameters) away, and the downstream disturbance was 30 feet
(9 1/2 diameters) away. Samples were taken at twelve traverse points
simultaneously with tests at the two inlet locations. Figure 30 is a
diagram of this location.
10) Converter slag return - During the converter cycle slag is periodically
poured off the matte. This slag is returned to the reverberatory
furnace. The fugitive emissions discharged during this process are
captured by a hooding system. These emissions were sampled from a
round horizontal duct 36 inches in diameter. The nearest upstream flow
disturbance was 100 feet (33 diameters) and the nearest downstream flow
disturbance was 25 feet (8 diameters) away. Samples were taken at 12
traverse points. Figure 31 is a diagram of this location.

Matte Tapping Fugitive Emission Duct
Samples from the matte tapping fugitive emission duct were taken from a
60" vertical duct located approximately 75 feet above the ground. Two sampl-
ing ports located at a 90° to each other allowed for horizontal traverses
during sampling. The nearest upstream flow disturbance was located 20 feet
(4 duct diameters) away from the sampling point. The nearest downstream dis-
turbance was located 10 feet (2 duct diameters) from the sample location.
Twenty-four traverse points were selected with twelve points on each traverse.
Figure 32 is a schematic of the sampling location.
Slag Tapping Fugitive Emission Duct
Slag tapping fugitive emission samples were taken through a 60" vertical
duct located approximately 75 feet above the ground. One sampling port was
utilized for both horizontal traverses during sampling. The nearest upstream
flow disturbance was located approximately 20 feet (4 duct diameters) away
from the sampling position. The nearest downstream disturbance was a bend
located 10 feet (2 duct diameters) away from the sampling location. Twenty-
four traverse points were selected with twelve points on each traverse.

SECTION 4
SAMPLING AND ANALYTICAL PROCEDURE
SAMPLING
The sampling train used in this testing program consists of a modified
EPA method 5 train (Figure 41). The trains used consisted of a seven
impinger system with 150 ml of deionzed water in each of the first two
impingers, an empty third impinger to minimize carry over, and a forth,
fifth and sixth impinger with 150 ml of 10% hydrogen peroxide in each.
The last impinger contained silica gel.
The sampling procedure was identical to that used in method 5, the
sample being collected isokinetically at the centers of equal area within
the duct.
SAMPLE RECOVERY
The sampling nozzle and probe liner were rinsed with 0.1 N NaOH and
brushed with a nylon bristle brush. The filter and impingers were then
removed to the mobile laboratory. The front half of the glass filter holder
was also rinsed and brushed with 0.1 N NaOH and that rinse was combined with
that of the probe and nozzle. The filter was then recovered from the holder
and placed in a polyethylene container, labeled and sealed. The contents of
the first two impingers were placed in a graduated cylinder and the volume
recorded. The impingers and connecting glassware were then rinsed with
0.1 N NaOH and the rinse combined with the impinger contents in a glass
sample bottle. During the test programs at Asarco in El Paso and Phelps-
Dodge in Ajo and Douglas, Arizona the third impinger was rinsed separately
and put in a glass sample bottle. Subsequent analysis of this rinse for
arsenic showed no significant amount present and this part of the recovery
was abandoned. During the test program at Asarco in Tacoma, Washington, a
rinse of the probe and first and second impingers with 15% HNO^ was applied
to selected tests at the direction of the EPA project officer in order to
determine the effectiveness of the 0.1 N NaOH rinse. The contents fourth,
fifth, and sixth impingers were measured and the contents combined in glass
sample bottles for later S02 analysis.
ANALYSIS
filter - The filter was placed in a 150 ml beaker and 50 ml of 0.1 N
NaOH was added and allowed to warm for about 15 minutes. Ten ml of
concentrated HNO? was added and brought to a boil for 15 minutes.
The mixture was then filtered through #41 Whatman paper, washed
with hot water and the filtrate returned to the hot plate to evaporate.
124
-------
When the solution was evaporated the beaker was removed from the hot
plate and allowed to cool. 0.1 N HMOs was used to redissolve the .
residue and solution transfered to a 50 ml volumetric flask and
diluted to volume. Many of the filters collected only small amounts
of arsenic and the entire volume was needed in the previous analysis
for arsenic by hydride evolution and were thus lost for purposes of
lead analysis.
2. Probe Wash and Impinger Solutions - Fifty ml of probe wash or impinger
solution was placed in a 150 ml beaker. Two ml of concentrated
HNOs is added and the beaker was placed on the hot plate and
allowed to evaporate,, When evaporation was complete the beaker was
allowed to cool and the residue redissolved with 0.1 N HN03 and
transfered to a'50 ml volumetric flask and diluted to volume.
3. Process Samples - About 0.2 grams of sample was weighed into a
tarred 150 ml teflon beaker and the weight recorded to the nearest
0.1 mg. Five ml of concentrated HNOs and 5 ml of concentrated
HF were added and the beaker placed on grating just above the hot
plate to prevent overheating of the teflon. The solution was
evaporated and the digestion was repeated until a light-colored
residue appeared. The residue was redissolved in 0.1 N HMOs and
transfered to a 50 ml volumetric flask and diluted to volume.
4. Atomic Absorption - The analysis was performed with an Instrumen-
tation Laboratories model 551 Atomic Absorption Spectrophotometer
equipped with a model 555 graphite atomizer for samples below 0.1
ppm lead. The analysis was performed at the 217 nm lead resonance
using a 1 nm bandpass and a 5 milliamp current to the lead hollow
cathode lamp. Samples with a concentration above 0.1 ppm lead
were analyzed using an air/acetylene flame. Samples below 0.1 ppm
lead were analyzed using the graphite furnace atomizer.
