Rougher flotation cells of Sarcheshmeh copper concentrator are expected to produce a concentrate assaying 7.6% with 96% recovery. Due to some reasons its recovery was decreased to 90% during last year. Moreover, its recovery is of great significant because 80% of the final tailings is disposed from this section. In this work, mineralogical surveying, size by size copper recovery analysis, reagents stage addition and dosage were investigated. It is shown that, in the +75 mu m size fractions in rougher tailings most of the free particles were chalcopyrite and pyrite minerals. The maximum recovery of copper was observed in 25-75 mu m fractions, while the major copper loss was in +105 mu m size fractions. It was found that, stage addition of collector (75, 13, 12) could improve the rougher recovery up to 2 percent.
