Copper Carbonate Ore Jun

Aug 21 2020 the method used to extract copper from its ores depends on the nature of the ore sulfide ores such as chalcopyrite cufes2 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.
