The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. ...

15. Type of Extraction of Minerals The process of taking out minerals from rocks buried under the earth's surface is called mining. Minerals that lie at shallow depths are taken out by removing the surface layer; this is known as open-cast mining. Deep bores, called shafts, have to be made to reach mineral deposits that lie at great depths.

The least reactive components can be replaced by the more reactive ones. Therefore, an element's reactivity accelerates the displacement reaction. Because of this, zinc can easily replace copper in a solution, but copper cannot. Because of this, when a zinc rod is submerged in the copper sulphate solution, its bluish tinge disappears.
