The process involves a series of flotation known as the differential flotation. In the flotation of copperzinc massive sulfide ores, flotation properties of copper and zinc are determined by the nature and composition of the ore. Copper zinc massive sulfide is even regarded as the most complex ore and consequently the most difficult to treat.

Seaman et al. (2012b) found that in order to obtain 70% pyrite recovery, the dosage of sodium sulfide was required to be as high as 460 g/t in a coppergold flotation plant. The activation mechanism of Na 2 S on the flotation of pyrite depressed in copper flotation is unknown.
New Reagent System Improves Recovery, Reducing Energy Use and Air Emissions in the Mining Industry. It flocculates fine material and may occlude fine coppersulfide particles. Lime increases the viscosity of the mineral slurry and tends to hinder aeration, slowing flotation kinetics. In addition, the calcium ion also has been shown to decrease recoveries of lead and molybdenumsulfides and to .

Production process was using by the process of grindingflotation. After grinding fineness, lime dosage, sodium sulfide dosage, collector and frother dosage, were determined by the open test. Closed circuit experiment was conducted by those optimal conditions identified in the above test, the recovery of copper concentrate is % and the grade of copper concentrate is %.
The copper concentrate grade that obtained by flotation process in China is over 20%, the recovery rate is about 88%; the foreign copper concentrate grade is about 25~40%, the recovery rate is 80~90%. Generally, the flotation process of copper sulfide ore is relatively simple.
