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.

Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

Copper Leaching Process. Copper leaching is a method used to extract copper from its ore through a process of dissolving it into a solution. This process is particularly effective for extracting copper from low-grade ores. It's an essential part of copper mining and processing that helps increase efficiency and reduce environmental impact.
