Extraction Of Copper | Mining, Concentration, Smelting

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 slagThe finely crushed ore is concentrated by Froth EXTRACTION OF COPPER IMPORTANT ORES OF COPPER Copper pyrite or chalcopyrite (CuFeS 2) Chalocite (Cu 2 S) or copper glance Malachite green [CuCO 3Cu(OH) 2] Azurite blue [2CuCO 3Cu(OH) 2] Bornite (3Cu 2 SFe2S 3) or peacock ore Melaconite (CuO) etc EXTRACTION OF COPPER FROM SULPHIDE OREEXTRACTION OF COPPER

copper extraction and purification chemguide

Extracting copper from other ores Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solutionNov 18, 2012· Conversion of Cu(II) ion into Copper metal via electrolysisExtraction of Copper from the Ore

Which ore is used for the extraction of copper metal?

Answer (1 of 2): Copper is extracted from various sulfide ores The most common are bornite and chalcopyrite, the others include tetrahedrite, native copper, covellite, chalcotite and some even more uncommon Copper can be theoretically extracted also from secondary copper minerals like malachitJan 01, 2018· A graph of mass of the ore used in the extraction against mass of the precipitate produced The results show that the amines and uric acids in chicken waste can complex copper ions from ores just like the acid leached solution Therefore the copper ions obtained from 60 g of the ore were later reduced by hydrazones species prepared in situCopper extraction by wet chemical method ScienceDirect
