Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining. ... In Phalaborwa in Limpopo province, copper ore is mined using open pit mining. This open pit is one of the world's largest open ...

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

Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cusulphide ore. The samples were ground as dry and wet with both ...
