Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.
From a processing point of view, copper ores could be divided into: Copper sulfide ores, where the pyrite content can vary from 10% to 90%. The predominant sulfide mineral in this ore is pyrite, but may also contain pyrrhotite and mar-casite. Some copper sulfide ores also contain significant quantities of gold and silver.

copper. Batch flotation tests were used to assess the performance in terms of mass-water recovery, sulphur grade-recovery and copper grade-recovery relationships and the Klimpel rate constant for copper recovery. The results showed that the di-ethyl-dithiocar-bamate (di C2-DTC) was the weakest collector of copper sulphide minerals.
