### Copper Mountain 65,000 t/d expansion approved including

The Copper Mountain mill flowsheet is currently a conventional two-stage crushing, SAG, pebble crusher, ball milling, and sulphide flotation circuit design. The current capacity supports 40,000 t per day of ore processing. The 45ktpd Expansion that is currently underway will add a third ball mill in parallel with the two existing ball mills.

Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the

The HPGR-ball mill circuit was estimated to require 75% of the energy of a standard semi-autogenous grinding (SAG) mill circuit. Even with an anticipated greater capital cost, the HPGR-ball mill circuit was found to give significantly better financial returns in all cases investigated in the feasibility study.
