3 stages of refining metallic minerals

Copper mining. The main stages. - School Science

Copper mines are only set up where there is more than 5kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. Roll over diagram of sequence, The flow chart shows you how copper is extracted from its ore and converted into pure metal. Roll over each stage to get a summary and click to...

Refining (metallurgy) - Wikipedia

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used...
