The recommended Pilot Plant would incorporate facilities to:
1. Receive R.O.M. coal having not more than 18" lumps into the
R.O.M. Hopper, deliver 1).00 TPH through the Reciprocating
Feeder to the Vibrating Screen, Rotary Breaker and Crusher
where the coal could be sized to I;" x 0 and finally to IV x 0.
2. Weigh and convey the IV x 0 raw coal to one of two steel silos,
each having a capacity of i|.000 tons. The capacity of the two
(2) silos will be adequate to store enough crushed raw coal
to run the preparation plant for one month at an average feed
rate of about $0 TPH for 22 days based on one shift per day.
Two separate silos would be provided for the preparation
plant to draw feed from one while the other is being loaded
with fresh coal either from the same mine which supplied the
.coal being washed or from a new, different mine. A belt
scale would be provided on the 30" Raw Coal Belt Conveyor
transporting crushed 1%" x 0 raw coal from the Rotary Breaker
to storage.
3> Weigh and hand sample the rejects for an approximate deter-
mination of the pyrite in the material reporting to the rock
bin.
Ij.. Convey IV x 0 raw coal from one of the silos through a Vibrating .
Feeder to the Ring Mill. The 2k" Conveyor to the Ring Mill is
provided with a belt scale to weigh the feed to the plant and a
suspended magnet to remove tramp irons. The Ring Mill will be
provided with two different cages to make it possible to crush
the coal to either 3/14." x 0 or to 3/8" x 0. To provide the
necessary flexibility for treating all of the different sizes of
crushed raw coal, an arrangement would be made to by-pass the
Crusher with the I's" x 0 raw coal. Although the plant has an
average capacity of 50 TPH, the 21)." H.M. Cycloid has a maximum
rated capacity of 75 TPH. In case there is a higher percentage
of fines (ll(>! x 0) in the raw coal, the proportion of fines in
the clean coal may become too great, making removal of moisture by
the centrifuge a problem. To overcome such an eventuality,
-------

raw coal crusher and increase the load to the H.M, Cycloid
to produce more coarse clean coal. This will help .to limit
the amount of fines to assure more efficient drying in the
centrifuge. . .
5. Wash a lower tonnage of coal in a H.M. Cycloid, by using an
alternative circuit with a 20" H.M. Cycloid. These two size
cycloids will also make it possible to demonstrate the
efficiency of washing of a same size coal in two different
sizes of cycloids.

also be provided so that it would be possible to change the
feed sizes going to the coarse coal section as well as to
the fine coal section. The following sizes of raw coal can
be washed in the two sections:

average feed rate of 50 TPH, the raw coal feed can be increased
to 75 TPH to increase the feed rate to the 21±" Cycloid. In
.the fine coal section, 3/8" x 0 or il]H x 0 raw coal goes .to.
the fine coal sump.
Rinse float (clean coal with low sulfur) from the H.M. Cycloid
to remove entrapped magnetite, centrifuge to remove some
surface moisture, weigh and load into a railway car with a
loading-boom..

9. Rinse sink (having high sulfur and ash) from the H.M. Cycloid
to remove entrapped magnetite and crush to a size of 3/8" x 0
or lij. M x 0 to liberate pyrite particles for further washing.
The crusher will be arranged to crush the following sizes of
sinks from the H.M. Cycloid: . '

"The crusher will also have a"by-pass arrangement to by-pass the
3/8" or smaller sinks without crushing.
10. Deliver dilute medium from the sinks and the float rinsing
screens to the thickener for thickening and finally to a
double drum-type magnetic separator for removing magnetite.
Concentrated medium flows to the heavy medium sump, which !
is fitted with a level controller to control the level of the-
sump; a densometer and recording controller will control and
record the specific gravity of the medium in'the Suinp. A
raw magnetite bin will respond to the level control to replenish
magnetite lost during.the process. -*
.11. Wash .crushed sinks from the.coarse coal washing section as well
as'the undersize raw coal from the raw coal screen in eight
8" Primary McNally-Vasman Tricones. Fine raw coal as well as
crushed sinks from the coarse coal washing section may be
washed in .the McNally Viaman Tricones to recover clean coal of
low sulfur content. There is an arrangement to by-pass the.
raw coal screen as well as H.M. Circuit, if coal only requires
treatment in the, fine coal circuit (McNally-Visman Tricones,
Diester Table & Flotation). If the coal is washed only in
the fine coal circuit, the rated capacity is expected to be.
35 TPH. The float (clean coal) from the McNally-Viaman Tricones
is classified in three ll\." Classifying Cyclones. Thickened

to remove a part of the 'surface moisture, following which
it will be weighed .and loaded into a railway car along with
the coarse clean coal. .
.12. Rewash sink from the Primary McNally-Visman Tricones either
in six 8" Secondary McNally-Visman Tricones or in one No. 7
Deister Coal Table or in both set up in parallel. This is
to separate light refuse particles from the heavy ones which
are expected to contain mostly pyrite. The two alternate
circuits are provided to determine the best washing efficiency
(to obtain a low sulfur coal and a pyrite rich refuse) either
by washing in the Secondary McNally-Visman Tricones at a high
specific gravity, or in a Deister Coal Table.
13» Rewash sinks (from the McNa^Lly-Visman Secondary Tricones) in
two (2) No. 6 Deister Ore Tables to determine if rewashing
improves the recovery of pyrite. The products from the
Secondary McNally-Visman Tricones, Deister Coal Table and
Deister Ore Tables, after proper sampling, are-pumped to a
settling cone to recover clarified water for use in the plant.
The underflow would be pumped into the'-waste pond.
114.. Pump the magnetite separator tailings, classifying cyclone
overflow and underflow drainage via the flotation feed sump
to the flotation cells to recover low sulfur fine clean coal.
The concentrate from the flotation cells .aftej? .filtration reports
with the clean coal in the coarse coal section for loading into
railway cars. Tailings from the flotation cells are pumped to
the settling cone for settling and recovery of clarified water
for use in the plant, and the underflow is pumped into the .
waste pond.
15. Sample all the streams entering into and coming out of each
different type of equipment. Composite samples will also be
taken of the feed entering into as well as products coming
out of the plant. There are twenty-nine sampling points, out
of which twenty-seven are automatic (solid and pulp).

SAMPLIHS & TESTING
Adequate testing arrangements have been provided in the plant
to evaluate each coal selected for processing, and to evaluate
.the performance of individual equipment as well as the whole
plant. The purpose of testing program is:
(a) To evaluate performances of each major piece
of equipment used in the plant.
(b) To evaluate each coal selected for processing.
(c) To evaluate overall performance of the plant for
cost analysis. . -

sulfur content balances for each candidate coal. =
In order to provide adequate test data, the plant will be provided
with twenty-nine (29) sampling points, twenty-seven (27) automatic
solid and pulp samplers and two manual sampling arrangements.
Raw Coal Tests; Approximately 8000 tons of each test coal will be
delivered to the plant. As the first 1^000 tons is crushed to
1*2" x 0, a raw coal sample will be collected during one to two
weeks prior to the start of each test.
" This sample will-be" collected by an automatic sampler, taking
increments at five minute intervals. A total of approximately
90 increments of ten pounds each will be collected each day with
alternate increments reporting to a primary sample and the
remainder to a reserve sample. Sampling will continue until a
minimum of lj.00 pounds of IV x 3/4" material is included in the
gross sample and 75$ or more of the first l|.000 tons delivered and
binned is sampled.
(The material reporting to the rock bin from the rotary breaker
will be weiphod, hand sampled, and analyzed for percent ash,

This will satisfy all conditions for ASTM D223l).-6$T on Mechanical
sampling of coal and Mj.92011.8 sailing coals classified according
to ash content. It will also provide the proper gross sample
to make the washability study from which plant settings can be
made.
The primary grosa sample will be screened to produce the following
sizes:
1*5" X 3/V'
3A" x 3/8"
3/8" x 1U. Mesh
IkM x 28 Mesh
28M x U8 Mesh
lj.8M x 0
Float and sink separations will be run on each size fraction at
the following, gravities: 1.3.0, 1-35, 1.1<.0, 1.50, 1.60, 1.90,
2.20, 2.50 and 2.80. The refuse will be visually examined to
see if heavier gravities are required.
Dry ash, total sulfur and pyritic sulfurs will be run on each size-
gravity fraction and composites calculated for each size which
might be used as feed to a piece of equipment in the cleaning
plant: -
IV x 3/8"
3/8" x 14 Mesh
IV x llj. Mesh
3/8" x 0
1UM x 0
The laboratory will be equipped wi.th sufficient equipment and
personnel to provide this data within the one week period before
the coal is to be tested.
Test Period Samples: Prom the data supplied, operating personnel
can anticipate an optimum setting for each piepe of equipment.
As a new coal is first fed to the plant, grab samples will be

collected to check the specific gravity of operation. When the
various circuits are set to the operators' satisfaction, daily
runs can be started to determine optimum plant conditions to
produce the maximum sulfur removal from the coal. In some cases
it is likely that it will be necessary to check more than one
set' of alternative conditions to determine the point of optimum
sulfur reduction.

(c) 70 increments will be collected because, although
ASTM specifies 35 increments for any analysis, 70
are required to obtain sufficient material for
screen tests.
Schedule: Normally for the circuit being tested there will be
one run made per day, broken into three segments. The morning
(A.M.) samples will consist of a 2 .to 2^ hour run and will be
removed from the samplers by 12:00 noon. This will require pre-
liminary morning work to be completed and the plant stabilized
no later than 9:30 A.M. (During the plant adjustment period

operator requests a "grab" sample for Float & Sink checks on
the adjustment of any piece of equipment).
The A.M. samples will be screened and floated to determine the
approximate washing gravity of the products from each cleaning
unit referenced to the raw coal data.
On all samples from morning test runs, the feed and product
samples will be screened, where sizes are available, at 3/U",
3/8", 114., 28,-l;8, 100, 150 and 200-mesh. -All. size-fractions of
feed materials and-dewatered clean and.refuse products applicable
to the circuit or circuits being tested will be subjected to
float and sink separations two gravities above and below the
anticipated gravity of separation.
The afternoon (P.M.) samples will be used only for material balance
of the plant in terms of percent ash, sulfur and pyritic sulfur.
Laboratory flotation tests will be made on all feeds to the flo-
tation cells, using reagents to be selected at a later date. All
size and gravity fractions as well as flotation fractions will
be analyzed for percent ash, total sulfur and pyritic sulfur.
All test work or daily runs will be completed no later than 5 A.M.
the following day, at which time the raw data will be fed to a
computer for processing. During separate circuit testing the
completed report for the previous day's run will be available for
operating personnel by 7:00 A.M.
Procedures for Processing Samples: The various automatic samplers
have been numbered on the plant flow sheet for the sake of orderly
planning and discussion of the treatment of individual samples.
A coded system will relate samples to samplers,, coal being processed,
testa run, size of product and date of test. It is anticipated

that drying of samples will be done by microwave techniques,
which is a process for continuous and rapid drying of wet
samples without induced heat.

5. Total Plant Circuit;
After the various plant circuits are set for their best
performance in sulfur reduction, at least three prolonged
runs will be made with all sampling stations of all
circuits in use so that a complete plant evaluation can
be made of each run. In addition to the sizing-gravity
separations, and ash, sulfur and pyritic analyses, actual
separating gravities and efficiencies of separation may
be determined together with plant material balances.
The plant feed and final cleaned coal products will have
a complete analysis made as shown on the attached CT&E
form to determine how removal of various components is
likely to alter burning and slagging characteristics of
the final product. A minimum of one run must be made
for the total plant after all circuits have been set at
optimum conditions.
NOTE: This means that for every coal tested there should
be a minimum of four test runs made at a single feed rate
chosen for each circuit in the plant. On the other hand,
triplicate runs could be made for each change in type of
feed or setting of equipment if confirming data is required
for statistical reliability. It would thus be possible
to make more than 100 runs on each type of coal delivered
to the plant without exhausting the technological capa-
bilities of the plant or the technical reasons for making
the test runs.

One of CT&E's Laboratories normally handling this type
of work. The cost of these additional analyses would
be at standard CT&E prices.
If deemed advisable, provision can be made at additional
cost to Include the following additional types of tests:
1 . Abrasiveness test of raw and clean coal products
to determine benefits of removing pyrlte.
2. Thermo-gravimetric and differential thermal analysis
to determine ignition temperatures and profiles of
raw and clean coal products.
3. Neutron activation analysis for trace elements of
raw and clean coal ash contents obtained by low
temperature ashing techniques. These data could be.
the basis for correlation studies of particulate
air pollution and high temperature reactions in
combustion gases.
Due to the volume of samples scheduled to be processed,
it is the intention routinely to sample makeup water and
plant effluent as well as any pond water or streams which
might be affected by the plant operation then to process
such samples in one of CT&E'3 Laboratories. Comprehensive

UNIT 62 - HEAVY MEDIUM COHTROLS
Page

TYPE: Pneumatic density and level control for heavy medium cycloid
circuit.
CYCLOID FEED DENSITY OPERATION
Recovered magnetite from magnetic separators, heavy medium from
float and sink screens, raw magnetite from the storage bin and
controlled diluting water passes through a "Halliburton" or
equal densometer via splitter box. The densometer sends air .
signal to the recording controller where specific gravity is
recorded on a 2lj.-b.our circular chart. The recording controller
sends air signal to a water control valve. An increase in density
causes the valve to open more, letting in more water to dilute
the medium. When medium density is low, the water valve is closed.
The density controller has measurement range of 1.00 to 2.00
specific gravity.
CYCLOID H.H. SOMP LEVEL OPERATION
The cycloid feed sump level is controlled by a differential pressure
cell (d/p cell) mounted on aide of the sump. The 'd/p1 cell is
calibrated to work from the operating level in the sump. If the
sump level drops below the operating level, the 'd/p1 cell will
send air signal to the level controller, which in turn will start
the raw magnetite feeder, Unit 61j.. The feeder will remain on
until the sump reaches the operating,level.
CONTROL CABINET
One (1) 12 gauge steel control cabinet is supplied to receive
compressed air supply and house controllers. Cabinet includes
pressure gauges, reducing valves and filter, copper tubing,
piping and conduit.
