  • What Is Copper Extraction

    What Is Copper Extraction

    Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market. Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation.

  • Pressure Cementation Process For Recovery Of Copper From

    Pressure Cementation Process For Recovery Of Copper From

    Copper bearing solutions are generally obtained from dump, heap, in situ, or vat leaching operations. All of these operations are based upon a dissolution of copper minerals in solutions containing sulfuric acid. The resulting copper bearing leach solution normally.

    Heap Leaching Gold And Silver Ores Onemine

    Vat leaching has been widely used by the copper industry on higher grade copper ores but has been used in only a few small operations on that size gold or silver ores. However, such a plant should be considered for a modest tonnage of a few million tons, 3 to 7 g per mt (0.10 to 0.20 oz per st), of Carlin-type leachable ores crushed to 9 mm.
