  • Copper extraction Wikipedia

    The process of liberation of copper ores depends upon whether they are oxide or sulfide ores Subsequent steps depend on the nature of the ore containing the copper and what will be extracted For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of theflotation and pyrometallurgical techniques Differentialflotation processes for mixed sulphides seldom giveascleanaseparation asdesired, andinsomeinstances flotation isquite unpractical (b)The successful industrial application of the copperselective solvent LIX4 5,eventhough used in the treatment ofoxide ores, provided the most significantA reviewofcopperhydrometallurgy SAIMMCopper is produced in the U S primarily by pyrometallurgical smelting methods Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining 1232 Process Description24123 Primary Copper Smelting
