FIGURE 3. Generalized mill flowsheet. Ore from the coarse ore bin would be reduced by jaw and cone crushers operating 8 hours each day, 5 days per week. Crushed ore would be conveyed to a fine ore bin and fed to a grinding section operating 24 hours per day. Rod and ball mills would grind the ore to minus 65 mesh, and jigs in series with

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.

Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.

Gold processing Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by ...
