Copper Ore
Copper ore usually contains about 0.5 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.
