The principle ore of copper is copper pyrite, C u F e S 2 and copper is extracted from this ore. Large amount of copper are obtained from copper pyrite (C u F e S 2 ) by smelting. Iron is present in the ore as trace metal. Option B is correct.
Bornite (3Cu2S.Fe2S3) or peacock ore. Melaconite (CuO) etc. EXTRACTION OF COPPER FROM SULPHIDE ORE. Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process.
The copper pyrite is partly converted into sulphides of copper and iron. 2CuFeS 2 + O 2 â†’ Cu 2 S + 2FeS + SO 2. 2FeS + 3O 2 â†’ 2FeO + 2SO 2. The Process in summary: The concentrated ore is heated stoutly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.
copper pyrite extraction - cafeole-koeln.de. Extraction of copper from copper pyrites involves the following steps. Crushing and concentration. The ore is crushed and then concentrated by frothfloatation process. Roasting. The concentrated ore is heated strongly in the reverberatory furnace, in excess of air.

the Gibbs free energy of formation of Cu2O is greater than that of CO. Hence, C can reduce Cu2O to Cu. Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction.

Aug 21, 2020· The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (C u F e S 2) 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.
Pyrite associated with the chalcopyrite remained unreacted during leaching of chalcopyrite and iron concentration in the final pregnant solution was found to be less than 20 mg/L. Copper recovery by sulfide precipitation from the leach solution as pure covelite was up to 99.1% at a Cu:S 2âˆ’ molar ratio of 1:1. Solvent extraction (SX ...
The Î” Go vs T lines for CO show negative slope at high temperature. Hence, it can easily reduce copper oxide to copper. However, Î” Gf for sulphide ores are higher than that for CS2 (which is an endothermic compound). Hence, the extraction of copper from pyrite ore is difficult.
Jun 17, 2007· Copper pyrite is called chalcocite, (Cu2S). It is a â€œsulfide oreâ€ as the copper is chemically bonded with sulfur.Other copper sulfide minerals in clued chalcopyrite, CuFeS2, bornite (Cu2FeS4), and covellite (CuS). The main copper oxide mineral is Cuprite, Cu2O.
Roasted copper pyrite on smelting with sand produces FeSiO 3 as fusible slag and Cu 2 S as matte. For removing the gangue, FeS, silica present in the lining of the Bessemer converter, acts as a flux and forms slag (iron silicate) on reaction with FeO. FeS Gangue + 3O 2 â€¦
the copper matte. Though, the slag can be easily separated from the desired product. Smelting is an exothermic reaction between copper pyrite ore, oxygen of air and fluxes (such as silica and limestone) at 1200 °C (above the melting point of copper, but below that of the iron and silica) to form a liquid called "copper â€¦
Jan 11, 2018· 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.
