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.

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. Copper is an example of this. Copper mostly occurs as sulfide ores, which are heated in air to convert them to copper II oxide.
