Major Mines & Projects | Mount Polley Mine

The mill at Mount Polley was commissioned in June 1997. The mill uses conventional rod and ball mills with a flotation and dewatering circuit to produce a copper /gold concentrate. The mill has a capacity to process 17,800 to 22,000 tonnes per day (tpd) of ore depending on hardness.

Ball Mill

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
