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.

      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).

       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.

                               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
    62
  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.
