How to Process Copper Ore Beneficiation Methods and

 · Copper ore beneficiation methods. Before the beneficiation of copper ores crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment and the final particle size of the copper ore is reduced to 0.15-0.2mm.

Leaching of Copper SulphidesSAIMM

 · Outotec s copper chloride leaching process is carried out in atmospheric leach reactors with cupric ions Cu(II) in a chloride media at a pH between 2 and 2.8. The leach conditions are suitable for the leaching of all copper sulphide minerals such as chalcopyrite bornite chalcocite covellite and digenite (Valkama 2013). These leach conditions have delivered high recoveries of copper and silver (95–98 and 93–96 respectively) in batch tests and pilot runs. Chloride from sodium chloride enables the leaching reactions but it is not consumed in them and sulphuric acid is used as a makeup acid. Because of the nature of the leaching solution and the subsequent SX neither chemical has stringent purity requirements. Silver and gold can be recovered also if they are present in the feed. As a result the technology is suited to a wide variety of copper-containing
