copper sulphide leaching process

Copper information provided by Copper Development …

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by

The rapid leach kinetics and high copper recoveries place FLSmidth ROL's process economics on par with stirred-tank leaching of secondary copper sulphide concentrates. The key to the high performance of the process is the use of very low energy, inter-stage or intra-stage attrition along with the activation of the mineral to enhance the selective dissolution of copper-bearing minerals.
