coal processing
Underground ROM Stockpile
Up to 4 Mtpa of Run of Mine (ROM) coal will be received and processed at Ulan Coal Mines Limited (UCML) Coal Handling and Preparation Plant (CHPP) from the Ulan Open Cut Mine.
The Ulan CHPP has a flexible, 1800 tph raw coal receivals system which allows either individual, or any combination of, direct plant feed, raw coal stockpiling or reclamation from the stockpile by a bucket wheel reclaimer.
A 1000 tonne surge bin distributes feed to a nominal capacity 1200 tph two module plant. The CHPP utilises dense medium baths, dense medium cyclones and water washing cyclones to separate rejects from thermal coal product for both the domestic and export markets.
Coarse rejects are trucked from a receivals bin and incorporated into the mining cycle. Tailings are thickened and pumped to reject emplacement dam.
Product coal is stacked onto product stockpiles and reclaimed by a 2000 tph rail mounted bucket wheel reclaimer to a 1750 t rail load out bin for rail transport to Eraring Power Station or the Port of Newcastle coal terminals.
