Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.

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.
