Advantages of ex traction of copper by sulphid ores

sulphide g ore treatment by leaching and flotation processapr , · problem with g recovery from sulphide ore how may a mill get the maximum recovery of g from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.this latter point is most important. in many cases a g mill using an allcyanide flowsheet with fine grinding of all the ore will report very low g content in the tailings particularly on anextraction of copper mining, concentration, smeltingcopper 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.a new way of extracting copper mit news massachusettsjun 28, · most current copper extraction processes burn sulfide minerals in air, which produces sulfur dioxide, a harmful air pollutant that has to be captured and reprocessed, but the new method produces elemental sulfur, which can be safely reused, for example, in fertilizers. the researchers also used electrolysis to produce rhenium and molybdenumextraction of copperthe 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 3.cu(oh) 2]. azurite blue [2cuco 3.cu(oh) 2]. bornite (3cu 2 s.fe2s 3) or peacock ore. melaconite (cuo) etc. extraction of copper from sulphide orehow is copper extracted from its sulphide ore? explain thethen electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. the impure copper is made anode and strip of pure copper are made cathode. on passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. an equivalent amount of copper is deposited on thedraw a diagram for electrorefining or purification of copper.during the process of electrolyte refining of copper, some metalssee more results (r ) the sulphide ore of copper reacts with its oxide to the give the metal 34.7 k+ views 1.7 k+ likes 1 copper mining and extraction sulfide oresthe smelter for sulfide ores produces sulfur dioxide gas. this is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. scrubbing sulfur dioxide also protects the environment. for example feo(s) + sio 2 (s) feo.sio 2bacterial consortium for copper extraction from sulphidethe mining industry is looking forward for bacterial consortia for economic extraction of copper from lowgrade ores. the main objective was to determine an optimal bacterial consortium from several bacterial strains to obtain copper from the leach of chalcopyrite. the major native bacterial species involved in the bioleaching of sulphide ore (acidithiobacillus ferrooxidans, acidithiobacilluscited by 8in the extraction of copper from its sulphide ore, thethe copper metal is mainly extracted from is sulphide ore copper pyrites (cufes 2) .the cup obtained can be reduced to copper by treating with cu 2 s. 2cu 2 s 3 o 2 2cu 2 o + 2so 2 switchsulfide ores an overview sciencedirect topicsif sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. again, as in figure 2.1.3 for the cuso system, the calculations are to oxidation by industrial oxygen so that the pressure of so 2 will be about 1 atm., except where oxygen pressure is appreciable nearcopper extraction if the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste (' gangue ') minerals. it is then concentrated using mineral flotation. the concentrate is typically then s to distant smelters, although some large mines have smelters located nearby.what is copper extraction?hydrometallurgical extraction sulfide ores. secondary sulfides those formed by supergene secondary enrichment are resistant (refractory) to sulfuric leaching. these ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite canextracting metals from sulfide oresextracting metals from sulfide ores. many important metals are present in nature combined with sulfur as metal sulfides; these include cadmium, cobalt, copper, lead, molybdenum, nickel, silver, and zinc. in addition, g and platinum group metals are associated with sulfidic base metal ores. the extraction of metals from their ores has been ansolvometallurgical process for extraction of copper fromdec , · extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. in this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and
