  • Ore - Wikipedia

    An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore …

  • The bioleaching of sulphide minerals with …

    The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach …

  • copper | Definition & Facts | Britannica

    Copper is commercially produced mainly by smelting or leaching, usually followed by electrodeposition from sulfate solutions. For a detailed treatment of the production of copper, see copper processing.The major portion of copper produced in the world is used by the electrical industries; most of the remainder is combined with other metals …

  • Copper extraction - Wikipedia

    All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.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 …
