extraction of metals introduction chemguide
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.

Copper Extraction from Sulfide Ores Latest Contents
This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.

O + 2SO 2 2Cu 2 O + Cu 2 S 6Cu + SO 2 The copper so obtained is called "Blister copper" because, as it solidifies, SO 2 hidden in it escapes out producing blister on its ...
GCSE CHEMISTRY Extraction of Copper Thermal ...
to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated. Thermal decomposition is an endothermic reaction.
Extraction of Copper at Elevated Feed Concentrations
of complex ores that contain copper. Very often, the plant will need to process a sulphide concentrate rather than an oxidised copper ore that is readily leached at ambient conditions. It is probably going to be using more aggressive oxidative leaching methods, for example, oxygen pressure leaching.
