Island Copper grinding circuit — a progress review ...

1986-5-1  The semiautogenous grinding circuit at the Utah Mines Ltd., Island Copper operation, located on Vancouver Island, British Columbia, is described. Since startup of the operation in 1971, grinding circuit throughput has been progressively increased from the initial design rate of 30 000 (33,000) to the current average 45 000 t/d (49,600 stpd) of porphyry copper ore. Key
