Copper Flotation - Mineral Processing Metallurgy

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 concentrate.

Chemical reactions between the native copper and surface waters resulted in new copper minerals coating the surface of the float copper such as green-colored malachite. Note that the float copper is smooth on both sides as compared to the 19-ton Lake Copper which is rough on the back because it was not carried by the glacier and thus, the glacial processes only smoothed the top side.
