Extraction of copper from ores

Update date: May 31

Nov 01, 2021 Hydrometallurgical processing is widely being explored as an alternative route for metal extraction because of its great potential to process complex and low-grade ores with reduced environmental impact. A few studies have been conducted on the processing of complex sulfide copper ores and carbonaceous copper ores

    Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added

    Dec 13, 2019 Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent)

    Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals

    Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent

    Mar 01, 2009 1.Introduction. Many important base metals such as copper, lead, iron, and zinc are present in nature combined with sulfur as metal sulfides, known as chalcopyrite, galena, pyrite, and sphalerite, respectively (Abraitis et al., 2004).The extraction of such metals from their ores has commonly been performed using mainly pyrometallurgical, hydrometallurgical, and biochemical
