copper extraction and purification - chemguide

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.
