The roasting cost works out at approximately 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 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

Rod Mills 911 Metallurgist

Rod Mills 911 Metallurgist

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.
