2021-6-7 · 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 ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide …
2021-9-17 · The compound present in the ore is copper (I) sulphide. Its formula is Cu 2 S. Copper is a less reactive metal; therefore, it is placed at the bottom in the reactivity series. Copper is extracted by heating its sulphide ore alone. Two steps involved in the extraction of copper metal from concentrated copper glance ore are: 1.
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 (sulphide ore) to give copper metal.Cu2S +2Cu2O → 6Cu +SO2 ↑In this process, Cu2S behaves as reducing agent.
Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting.
In the extraction of copper from its sulphide ore, the metal is final…

A slag is an easily fusible material which is formed when gangue still present in the roasted or the calcined ore combines with the flux. For example, in the metallurgy of iron, CaO (flux) combines with silica gangue to form easily fusible calcium silicate (CaSiO 3) slag. CaO + …
The most suitable method for extraction of copper from low grade sulphide ore is. Apne doubts clear karein ab Whatsapp par bhi.
In the extraction of copper from its sulphide ore, the metal is formed by reduction of Cu 2 O with: CO. SO 2. Cu 2 S. FeS. C. Cu 2 S. The 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.
2012-7-24 · 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 hydro-metallurgical process. For latest information, free computer courses and high impact notes visit :
Then 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.
