Segregation Process of Mixed Sulphide Copper Ore

Sulphide copper ores are normally concentrated by flotation while the oxide ores undergo hydrometallurgical treatments. The mixed sulphide-oxide copper ores may be processed by combined methods such as flotation followed by leaching and precipitation of the oxidized portion, or vice-versa.

Extracting copper. Extracting copper.

Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.
