Copper Ore Beneficiation Plant
Nov 01, 2019 Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates.
