extraction of copper from its sulphide ore in arab

Extraction of copper directly from sulphide ore is less favourable than from its oxide through reduction Explain asked Dec 18 2017 in Chemistry by sforrest072 127k points

Sulfide ores are generally processed using pyrometallurgy the extraction and purification of metals by processes involving the application of heat This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores in four basic steps 1 froth flotation 2 thickening 3 smelting and 4

In the extraction of copper from its sulphide ore when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S sulphide ore to give copper metal Cu 2 S 2Cu 2 O → 6Cu SO 2 ↑ In this process Cu 2 S behaves as reducing agent copper extraction from ore

AnswerIn the extraction of copper from its Sulphide Ore when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal In this process Cu2S behaves as reducing agent 2Cu2S3O2heat→2Cu2Os2SO2g 2Cu2OCu2Sheat→ 6CusSO2g In electrolytic refining of copper the

On industrial scale copper is extracted from its sulphide ore known as copper pyrite CuFeS 2 by smelting method

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 hydrometallurgical process For latest

Extracting copper from its ores The 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

Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate carbonate or sulphate ores Getting copper from chalcopyrite CuFeS 2 Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of copper

The cathodes are 9999 pure copper The blister copper anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution This is driven by a low voltage of about 13V and so the process is safe

Extraction and refining The extraction of nickel from ore follows much the same route as copper and indeed in a number of cases similar processes and equipment are used The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production
