Grinding and concentration together consume about 45 percent of the energy used in the pro-duction of cathode copper. Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrat-ing 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of cath-
May 16, 2016 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 sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper
Froth flo- tation is the prevalent concentration method in the copper industry it separates the pulverized ore (containing around 0.6 to 2.0 percent cop- per) into concentrates (with 20 to 30 percent cop- per) plus tailings (wastes of 0.05 to 0.1 percent copper) .40.
