The Mineral Copper

Half of the world's copper deposits are in the form of chalcopyrite ore. Ores are removed either by open-pit or by underground mining. Ores containing as little as .15% copper can be mined profitably in open-pit mining, but underground mining is profitable only if an ore contains 6% to 7% copper.Get price
