  • Copper Mining and Extraction Sulfide Ores
    Copper Mining and Extraction Sulfide Ores

    About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper aresulfidesand oxides.

    Copper Mining and Extraction Oxide Ores

    Copper Mining and Extraction: Oxide Ores. Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction:Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

    Copper Mining: The commonest ore used in the extraction of copper isChalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

    Theextractionofcopperfromoreis normally carried out in three major steps. The first step, mineral processing , is to liberate thecopper mineralsand remove waste constituents—such as alumina, limestone, pyrite, and silica—so that thecopper mineralsand other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percentcopper.
