Abstract

The purpose of this study was to investigate the influence of grinding pulp pH and solid content on the performance of rougher flotation of Sarcheshmeh copper sulphide ore by a series of batch flotation tests. The results indicated that pH and solid percentage had extremely significant effect on recovery and grade of copper. Copper recovery of rougher cells strongly increased with increasing the pH and solid content, while as expected copper grade of rougher flotation reduced. In addition, the results demonstrated that maximum separation efficiencies are obtained in solid percentage, 55 and pH, 8, respectively. Finally, regression equations were proposed for correlation between recovery and grad of Cu with pH and solid content of grinding slurry.
