Processing of sulphide copper ore is by conventional comminution, grinding and flotation to produce a clean copper concentrate. The copper concentrate is trucked to a storage facility located at Port Hedland, approximately 350km from Nifty, where concentrate is accumulated before shipping for smelting and refining.
The invention relates to a method for processing pyritic copper sulphide concentrate, in which, in addition to copper, there is arsenic and gold bound to the sulphide minerals, or invisible gold process used concentrate chalcopyrite ore - danceouteu
Some new players have joined the list of hydromet processes for copper sulphide concentrates. A key driving force is increasing industry concerns in the transporting and smelting of concentrates with high impurity levels, especially arsenic. This has led some to focus on removal of impurities rather than total hydromet processing.

Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore. Recovery from copper-cobalt sulfide concentrates. The ores are treated by a
