Sulfide ores are more important commercially. Half of the world's copper deposits are in the form of chalcopyrite ore. Ores are removed either by openpit or by underground mining. Ores containing as little as .15% copper can be mined profitably in openpit mining, but underground mining is profitable only if an ore contains 6% to 7% copper.
