  • Extraction Of Copper Mining, Concentration, Smelting

    The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. 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. Concentration of Ore: The ore is crushed into a fine powder and a suspension is

    As in any other extraction problem, there are two basic approaches to the recovery of bitumen from tar sands. In one case, the ore can be mined and transported to a processing plant where the bitumen is recovered. Alternately, the extraction of the bitumen can be accomplished “in-situ.” Over the last 50 years, a great variety of extraction processes, including both surface mining and in

    Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy- heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy- froth floatation, thickening
