The Processing of Copper Ore Beneficiation
The copper ore beneficiation plant uses three processes: crushing, grinding and beneficiation. It's just that the selection of individual copper ore processing equipment and beneficiation technology will be slightly different. Among them, in the crushing process, the use of three-stage closed-circuit crushing can well complete the work of ore ...

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.
