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.

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. 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. Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining. Note: You will find a brief description of froth flotation on the introduction to metal extraction page. The concentrated ore is heated strongly with silicon dioxide silica , calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper II ions in the chalcopyrite are reduced to copper I sulphide which is reduced further to copper metal in the final stage.

In the extraction of copper from its sulphide ore

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. An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. The extraction close extraction The process of obtaining a metal from a mineral, usually by reduction or electrolysis. In principle, any metal could be extracted from its compounds using electrolysis close electrolysis The decomposition breakdown of a compound using an electric current. However, large amounts of electrical energy close electrical energy Energy transferred by electricity. If a metal is less reactive close reactive The tendency of a substance to undergo a chemical reaction.
