High-Oxidation-Rate Complex Copper Ore

     

Beneficiation Method for High-Oxidation-Rate Complex Copper Ore Containing Paragenetic and Associated Metals:

This method comprises the following steps: grinding the run-of-mine ore and conditioning it into Pulp 1; subjecting Pulp 1 to copper sulfide flotation to obtain Copper Sulfide Concentrate 1, copper sulfide middlings and copper sulfide tailings; subjecting the copper sulfide tailings to copper oxide flotation to obtain Copper Oxide Concentrate 1, copper oxide middlings and copper oxide tailings; and separately cleaning the copper sulfide middlings and copper oxide middlings to obtain Copper Sulfide Concentrate 2 and Copper Oxide Concentrate 2 respectively.

Through separate treatment of the middlings, both high-grade and low-grade copper sulfide concentrates, as well as high-grade and low-grade copper oxide concentrates, are produced. By sorting the high-grade and low-grade copper sulfide and copper oxide concentrates, the subsequent metallurgical process flowsheet is simplified, copper recovery is improved, the recovery of paragenetic and associated metal resources (especially precious metals) is enhanced, production costs are reduced, and economic benefits are boosted.
