Copper Ore Processing Plant
Ore processing flow: 1 Crushing: Use stone crushers to crush the copper ore to 0–5 mm or 0–9 mm. 2 Washing: Use a spiral classifier to wash away the clay and screen out copper ore with a qualified particle size. 3 Grinding: The electromagnetic feeder sends the copper ore with qualified particle size to the ball mill for grinding.

Copper Processing | Multotec
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
