  • Copper Mining and Extraction: Oxide Ores

    In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction Electrowinning). The acid would have to be made anyway as it would be environmentally unacceptable to release sulfur dioxide gas into the atmosphere.

    Copper extraction Wikipedia

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value.

    Copper recovery using leach/solvent extraction

    Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a catalytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers Exploration and Development Corporation, came on line1. Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching

    Heap leaching Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.
