In the extraction of copper from its sulphide ore

Sulphur dioxide S O 2. Iron sulphide FeS. Carbon monoxide CO.

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!

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.

Write the reaction involved. Draw a labelled diagram of the electrolytic cell used for the refining of copper. Explain the variour steps supported by chemical equations. Draw labelled diagram from the electrolytic refining of copper. Explain the various steps supported by chemical equations. Given below are the steps for extraction of copper from its ore.

Name the metal which is extracted from the ore called 'Rock salt' b Name two ores of zinc. Write the names of the chemical compounds present in them and give their chemical formulae. Give equation of the reactions involved. Name the main ore of mercury. How is mercury obtained from its ore? Byju's Answer.

In the extraction of copper from its sulphide ore

Crushing and concentration: The ore is crushed and then concentrated by the froth-flotation process. Roasting: The concentrated ore is roasted in excess of air. During the process of roasting,. Copper pyrite is partly converted into sulphides of copper and iron. Smelting: The roasted ore is mixed with powdered coke and sand and is heated in a blast furnace to obtain matte and slag.

It does not react with water, and is easily bent into shape. C Carbon monoxide CO. Contributors and Attributions Jim Clark Chemguide. This is a colou Explain the variour steps supported by chemical equations. Which of the following pairs of metals is purified by Van Arkel method Write the reaction involved. View Solution. Electrolytic Refining The purification uses an electrolyte of copper II sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. The Process The concentrated ore is heated strongly with silicon dioxide silica and air or oxygen in a furnace or series of furnaces.

Unreactive close unreactive A substance is unreactive or inert if it does not easily take part in chemical reactions. However, most metals are found combined with other elements to form compounds close compound A substance formed by the chemical union of two or more elements. Most metals are extracted from ore close ore A rock containing enough quantities of a mineral for extraction to be possible.

Name the type of ore with one example. Subject Chosen Chemistry. For every zinc ion going into solution there will obviously be one fewer copper ion formed. Also show the ions present in them. This is a colou It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. Give two examples of alloys. During electrolytic refining of copper some metals , present as impuri UK pound coins and the gold-colored bits of euro coins are copper-zinc-nickel alloys. Given below are the steps for extraction of copper from its ore. Any metal in the impure anode which is below copper in the electrochemical series reactivity series does not go into solution as ions. Write the balanced equations involved in the process.
