The rod mill and two ball mills are approximately the same size for simplified maintenance. Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated

Finally, a frother transforms the mixture into a thick layer of bubbles, which overflows from the ball mill tanks into collection troughs. The bubbles condense and the water drained off, leaving a mixture called copper concentrate. The mixture contains 25-35% copper, in addition to copper and iron sulfides and small bits of gold, silver and other matter. The leftover waste—known as tailings

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density. The underflow from the cyclones is sent back to the mill to be reduced further in size, generally
