In the extraction of copper from its sulphide ore, the metal finally obtained by the reduction of cuprous oxide with Iron II sulphide Carbon monoxide Copper I sulphide Copper I sulphide. Carbon Silicon Phosphorus Phosphorus.

For every zinc ion going into solution there will obviously be one fewer copper ion formed. The copper II ions in the chalcopyrite are reduced to copper I sulfide which is reduced further to copper metal in the final stage.

Given below are the steps for the extraction of copper from its Sulphide ore: a Concentration of the ore : Removal of unwanted metals and gangue to purify the ore is done by Froth floatation method as it is a sulphide ore. 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. Tutorialspoint Simply Easy Learning.

Jump to navigation. The most common types of ore, copper oxide and copper sulfide , undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper.

In the extraction of copper from its sulphide ore

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 - It is worthwhile spending some time sorting out what the reducing agent is in these reactions, because at first sight there does not appear to be one! Or, if you look superficially, it seems as if it might be oxygen!

Why is the use of diesel and petrol as fuels in automobiles being repl Identify the alloy containing a non metal as a constituent in it Draw labelled diagram for the electrolytic refining of copper. In the extraction of copper from its sulphide ore, the metal finally obtained by the reduction of cuprous oxide with Iron II sulphide Carbon monoxide Copper I sulphide Copper I sulphide. For every copper ion that is deposited at the cathode, in principle another one goes into solution at the anode. Text Solution. Switch Flag Bookmark. View Solution. While extracting copper from its sulphide ore, the metal is finally obtained by the reduction of C u 2 O with :. Also show the ions present in them.

Crushing and concentration: The ore is crushed and then concentrated by the froth-flotation process.

It is a good conductor of heat and does not react with water. The ores typically contain low percentages of copper and have to be concentrated before refining e. Which iron compound is present in this ore? Draw labelled diagram for the electrolytic refining of copper. All that happens is that there is a transfer of copper from the anode to the cathode. Explain with equations of the reactions involved. Once again, the sulfide ions are acting as the reducing agent. Metals above copper in the electrochemical series like zinc will form ions at the anode and go into solution. What steps will be required to obtain metal from the enriched ore? But that's silly! How is copper extracted from its sulphide ore? Which of the following pairs of metals is purified by Van Arkel method Roasting of sulphides gives the gas X as a byproduct.
