Preparation Plant
Twentymile Coal constructed a preparation plant during 1994 and 1995 which is used to wash the existing low quality
coal stockpiled in the Low Quality Coal Stockpile and low quality coal currently produced from the mine. The Low
Quality Coal Stockpile is traversed along the northwest by a haul road. Ramps maybe constructed along the southeast
and southwest perimeters of the pile at the spoiUcoal interface as necessary to move material to the plant. The
preparation plant and associated facilities are constructed generally north of the existing low quality coal stockpile.
As of May, 1999, TCC had exhausted all of the previously stockpiled low quality coal. It is now planned to run the
plant per the originally thought time frame of April though October, unless conditions dictate it is run all year. In
order to accommodate this schedule, approximately 200,000 - 400,000 tons of material has to be stockpiled near the
existing grizzly prior to being processed through the plant during the milder part of the year. The location of the
stockpile is shown on Map 24.
The material will be transported by a front-end loader from its stockpile to the grizzly. The material will then be
processed through the plant. Product will be incorporated into TCC's product stockpile and this refuse will be hauled
to the refuse pile.
The preparation plant is of metal construction and straddles the existing overland belt. The prep plant was designed to
process approximately 250 tons per hour, and the anticipated operating season is from April through October.
Production needs may vary this anticipated schedule. The preparation plant uses a heavy media (magnetite) to
separate the coal from the rock. Two magnetite storage bins (50 and 100 tons) are located adjacent to the plant. A
reclaim tunnel, prep feed conveyor belt, and hopper are constructed for transferring the low quality coal to the prep
plant. A thickener tank is constructed adjacent to the prep plant. An emergency overflow sump is constructed near
the prep plant in the event a power outage occurs and the thickener has to be dumped out of the system. The sump is
sized to hold the thickener and allow for a foot of free board. In the event the thickener has to be dumped the material
will be pumped back into the system or over to Pond D. A small transformer pad will be constructed next to the prep
plant.
