copper concentrate processing

Copper Metals X Limited

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.
