Get PriceThe copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air Cu2 S O2 → 2Cu SO2 The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves
Get PriceCopper is extracted from sulfide ores or concentrates by electrolysis in a cell having separate anode and cathode sections and having an intermediate liquid copper mercury alloy electrode
Get PriceLeaching for copper extraction generally works by dripping a dilute acid solution through piles of ore to create an environment in which rock eating and iron oxidizing microbes known as lithotrophs and ferroxidants can naturally break down and oxidize the ore The resulting copper rich solution is then processed to produce high purity copper
Get Priceii Copper matte contains Cu 2 S and FeS In the blast furnace copper matte is added with powdered coke and silica The oxidation of ore takes place in this process As a result cuprous oxide and ferrous oxide are produced The role of silica in this process is to remove the iron oxide obtained as slag
Get PriceA mining company estimates that the marginal cost of extracting x tons of copper ore from a mine is 0 6 0 008 x measured in thousands of dollars per ton Start up costs are $ 120 000 What is the cost of extracting the first 50 tons of copper What is the cost of extracting the next 50 tons We have an Answer from Expert
Get Price1 Copper is refined from ores in the ground either through underground or open pit mines Most of the copper ores mined today are oxide or sulfide ores Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 11 14 but is introduced here because an important by product of this process is used for the extraction of oxide ores
Get PriceExtraction of Copper It is mainly extracted from copper pyrites CuFeS2 The sulphide ore is usually of very low grade and contains iron sulphide gangue and smaller quantities of arsenic antimony selenium tellurium silver gold and platinum The various steps involved in the extraction are 1 Crushing and concentration
Get PriceBacteria feed on the low grade metal ores and form a solution of copper ions called a leachate Slow process it can take years to extract 50% of the metal from a low grade ore Energy is needed in the elctrolysis step Then the copper will be extracted from the leachate by electrolysis or scrap iron
Get PriceBest answer In 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 2Cu2S 3O2 heat→2Cu2O s 2SO2 g 2Cu2O Cu2S heat→ 6Cu s SO2 g
