The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

Based on the gold recovery and mineral processing techniques required, gold ores are commonly classifi ed into two major categories: free-milling and refractory ores. Typically, free-milling ores are defi ned as those where over 90% of gold can be recovered by conventional cyanide leaching. Refrac-tory ores give low gold recoveries or give ...
