Extractive Metallurgy of Copper ScienceDirect

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. The other 20% is produced by heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores.
