Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Mineral processing - Wikipedia

Concentration. There are a number of ways to increase the concentration of the wanted minerals: in any particular case, the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.
