‚ÄčAll run of mine (ROM) coal extracted from West Wallsend Colliery is processed at the Macquarie Coal Preparation Plant (MCPP). Blended coal from the raw coal stockpile is fed into the MCPP via a conveyor. Coal is screened, separated according to size and rinsed. Coal is then deposited onto the energy and coking coal stockpile according to coal quality.
