Extractive Metallurgy of Copper | ScienceDirect
The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu to 1 or 2% Cu. Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copper-from-ore is produced by concentration/smelting/ refining of sulfide ores.

Gold processing
Extraction and refining Amalgamation. Elemental gold (and silver as well) is soluble in mercury, so that, when particles of the metal are brought into contact with a fresh mercury surface, they are wetted and dissolved, forming an alloy called amalgam. This phenomenon is exploited for the recovery and concentration of fine particulate gold or ...

Extraction of Metals – Concentration, Reduction and Refining
The extraction of metal also needs proper refining to remove the impurities which a metal absorbs through all the chemical-based procedures. An electronic refining apparatus is used for the refining procedure, which provides 99.9% pure metal. Conclusion: The extraction of metals is a long procedure that requires the study and knowledge of metals.
