  • Extraction Of Copper | Mining, Concentration, Smelting

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (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 Concentration of Ore: The ore is crushed into a fine powder and a· Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 999% purity Copper can be recycled indefinitely without the base metal being compromisedCopper Smelting Process Furnaces Used, ByProducts, andThe flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a benchscale testing regime The processing of the test ore was problematic due to a mineral assemblage that caused prevalent slime generation Fundamental adsorption, microflotation and EhpH tests were conducted on pure minerals to investigate mineralAN INVESTIGATION OF COPPER RECOVERY FROM A SULPHIDE
