Copper Ore an overview ScienceDirect Topics
Copper ore usually contains about to 2 copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.
Copper ores have been mined for at least 5 000 years because it is easy to get the copper out of them. For example if a copper oxide ore (CuO) is heated in a wood fire the carbon in the charcoal can reduce the oxide to metal Making pure copper. Extremely pure copper (greater than ) called electrolytic copper can be made by electrolysis.
