Most important copper beneficiation techniques are froth flotation, gravity separation, and acid leaching processes. Usually.

Beneficiation process of copper ore - FDM

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene).
