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. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.Chat Online

Copper extraction by froth flotation process 183 copper extraction by froth flotation process offers 2435 copper ore concentrate products. about 10 of these are copper ore, 1 are separation equipment. a wide variety of copper ore concentrate options are available to you, such as is concentrate, nonconcentrate. chat now
Steps involved in the extraction of iron ore. available for the extraction of gold metal from its ores. amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. this process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen.
Extraction of iron amp concentration of ore an overview. the extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. the common ores of iron are iron oxides. these oxides can be reduced to iron by heating them with carbon in the form of coke.
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.
The carbonates ores are changed into oxides by heating strongly in the presence of excess air. this process is known as calcination. the reaction is given below znco 3 heat zno 2co 2. c. electrolytic refining many metals such as copper, zinc, silver, gold, copper are refined electrolytically. for example at cathode cu 2 2e cu
The gibbs free energy of formation f g of cu 2 s is less than that of h 2 s and cs 2.therefore, h 2 and c cannot reduce cu 2 s to cu.. on the other hand, the gibbs free energy of formation of cu 2 o is greater than that of co. hence, c can reduce cu 2 o to cu.. c s cu 2 o s 2cu s co g. hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore ...
