The chief ore of copper is chalcopyrite (CuFeS2). This ore is found in many different forms worldwide but is most commonly found as a crystalline mineral. It is yellow-green with a metallic luster and can sometimes contain other metal sulfides such as pyrite or galena. The metal content of this ore ranges from 30% to 80%. Because of its high ...
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2.
Extracting copper from copper oxidea Transfer one spatula measure of copper(II) oxide to a hard glass test-tube.b Carefully add one spatula of charcoal powder on top of the copper oxide without …
In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with: copper(I) sulphide; sulphur dioxide; carbon monoxide; iron(II) sulphide; A. copper(I) sulphide. B. carbon monoxide. C. sulphur dioxide. D. iron(II) sulphide. Open in App. Solution.
Q. Aluminium and copper are extracted from their oxide and sulphide ores respectively.Which of the following is correct ? I. Copper is extracted by the auto reduction of copper oxide by copper sulphide. II. Aluminium cannot be obtained by chemical reduction due to its strong affinity for oxygen.
In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S to give copper metal. In this process, Cu 2 S behaves as reducing agent.. 2Cu 2 S+3O 2 +heat→2Cu 2 O(s)+2SO 2 (g). 2Cu 2 O+Cu 2 S+heat→ 6Cu(s)+SO 2 (g). In electrolytic …
Hence, oxide ores of copper can be easily reduced to copper by heating with coke. The Δ G o vs T lines for CO show negative slope at high temperature. Hence, it can easily reduce copper oxide to copper. However, Δ G f for sulphide ores are higher than that for C S 2 (which is an endothermic compound). Hence, the extraction of copper from ...
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 ores are the commonest …

This is how an extraction process is designed. Every constituent is analysed and then the most suitable process of separating it from the rest is chosen. The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers.
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following …
Copper ores are generally oxides or sulphides. - In the extraction of copper (I) sulphide, there are mainly five steps involved.
