Copper Flotation - Mineral Processing Metallurgy

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 ...

Low grade ores – Smelt, leach or concentrate? - ScienceDirect

Jan 01, 2010  In the case of copper, if no additional grinding of the ore is required as the ore grade falls then concentrating and smelting is the preferred route where pyrometallurgical processing can be applied. However, if fine grinding is required (down to 5 μm) then the preferred routes are heap leaching and direct smelting, in that order. In situ ...
