  • Copper Smelting Chemistry Tutorial

    Mining produce ores containing 2 or less of copper. Concentrating the ore by froth flotation can result in ores with up to 35 copper. A collector oil such as an organic xanthate or thiophosphate is added to the powdered ore and adheres strongly to the chalcopyrite particles making them water repellant.
