The processing plant has a rated raw coal feed capacity of approximately 600 tonnes per hour. Heavy media cyclones are used for coarse raw coal cleaning and flotation is used for fine raw coal cleaning to produce clean coal products.
Run-of-mine (ROM) coal is delivered by truck to an existing ROM coal stockpile. ROM coal is reclaimed using vibratory feeders, located in a reclaim tunnel. The feeders load the ROM coal onto a reclaim conveyor that transfers the coal into the breaker station. Initial coal processing is conducted through the rotary breaker where the coal is sized to minus 38 millimeters. Oversize material, mainly rock, is conveyed to an open, on-ground storage pile and then trucked to the existing coarse reject disposal facility. After the removal of the oversize material in the breaker, the plant feed is conveyed to the 1,800-tonne raw coal silo. Raw coal is recovered from the silo by four vibratory feeders onto the coal processing plant feed conveyor, which is equipped with a tramp iron magnet and a belt scale, and conveyed to the desliming section of the processing plant.
The raw coal feed is divided and distributed over eight sieve bends that discharge directly to eight desliming screens. The deslimed coarse coal then passes to a mixing box where it is mixed with water and magnetite and fed to eight 600 millimeter diameter heavy media cyclones. The fine coal screen underflow is pumped to a distribution box and then pumped to the froth flotation circuit.
