3. Processing of Copper Ore
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.
