Copper Extraction Process Demystified: Expert Insights
Magnetic Separation: Magnetic separation is a process of concentrating the desired material by the use of a magnetic field. In the context of copper extraction, this method is employed to separate iron sulfides from copper sulfides. The crushed and ground ore is then taken through a magnetic separator which has strong magnetic fields.

Copper Processing
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.
