INCREASING SAG MILL CAPACITY AT THE COPPER
2018-2-20 Copper Mountain first feed to the SAG mill occurred in late May, 2011. The circuit began ramp up in mid-June of that year, with more consistent operating run times on the SAG and Ball mills. Plant throughput in the first months was quite variable with throughput tonnage greater than 40,000 tons one day and less than 25,000 the next on some occasions.
