final products of copper mining and their compositions

Copper Chemistry

Copper later played an important role in the advent of electricity and today is still among our most valued materials. Usage of copper compounds also dates back to before 4000 BC. Copper sulphate for example was an especially important compound in early times. Ancient Egyptians used it as a mordant in their dyeing process.

Copper Production: How Is Copper Made? - The Balance

Sep 26, 2019· Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
