Extracting copper from its oresThe method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 ) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag

May 15, 2020 (ii) copper sulphide is partially oxidised to cuprous oxide which further reacts with remaining copper sulphide to form copper and sulphur dioxide. 2 Cu 2 S + 3O 2 → 2Cu 2 O + 2SO 2. Cu 2 S + 2Cu 2 O —- 6 Cu + SO 2. After the reaction has been completed, the converter is tilted and the molten copper is poured into sand moulds
Compounds of Copper Blue vitrol is also known as copper sulphate pentahydrate, roman vitrol, salzburg vitrol, copper sulphate 5-water etc.blue vitrol contain 25.45% copper, 4.04% hydrogen, 57.67% oxygen and 12.84% sulphur.Blue vitrol is used in electroplating as well as electrorefining of metal.
