Reduction of copper I oxide with copper I sulphide:. Menu Categories. Explain the steps for the extraction of copper from its sulphide ore. Write the balanced equations involved in the process.

In the extraction of copper from its sulphide ore

In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with. 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 sulphide ore to give copper metal. In the extraction of copper from its sulphide ore, the metal finally obtained by the reduction of cuprous oxide with. Reduction of Copper oxide done with Copper I sulphide. Which of the following elements is present as the impurity to the maximum extent in the big iron? Book Chosen Chemistry I. Subject Chosen Chemistry. Book Store Download books and chapters from book store. Currently only available for. Class 10 Class Copper I sulphide Cu 2 S 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 sulphide ore to give copper metal.

During electrolytic refining of copper some metalspresent as impuri However, they won't get discharged at the cathode provided their concentration does not get too high.

The method used to extract copper from its ores depends on the nature of the ore. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining e. The concentrated ore is heated strongly with silicon dioxide silica and air or oxygen in a furnace or series of furnaces. The copper I sulfide produced is converted to copper with a final blast of air. The end product of this is called blister copper - a porous brittle form of copper, about 98 -

This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.

D Copper I sulphide C u 2 S. Extracting of Copper from Other Ores Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper II sulfate solution. You have to use some chemical knowledge as well. Explain the steps for extraction of copper from its sulphide ore. The cathode is either a strip of very pure copper which the new copper plates on to, or stainless steel which it has to be removed from later. Describe electrolytic refining of copper with chemical equations. While extracting copper from its sulphide ore, the metal is finally obtained by the reduction of C u 2 O with :. Iron sulphide FeS. Explain the various steps supported by chemical equations. Which iron compound is present in this ore? However, they won't get discharged at the cathode provided their concentration does not get too high.
