Optimizing the leaching conditions of chalcopyrite/pyrite concentrate in Sarcheshmeh Copper Complex using response surface methodology

Abstract In the current study, the leaching conditions of chalcopyrite/pyrite concentrate were optimized by sulfuric acid and hydrogen peroxide using response surface methodology (RSM). The optimal leaching conditions were found to be a sulfuric acid concentration of 150 g/L, a hydrogen peroxide volume of 350 mL, a temperature of 80 °C, a leaching time of 8h and a solid–liquid ratio of 0.52 g/mL. After analysis of variance (ANOVA), the sulfuric acid concentration and temperature were the most significant process variables for the leaching concentrations of both copper and iron. Under the optimum conditions, the recovery of copper and iron was 81.83% and 67.57%, respectively.

期刊介绍： Chemical Engineering Communications provides a forum for the publication of manuscripts reporting on results of both basic and applied research in all areas of chemical engineering. The journal''s audience includes researchers and practitioners in academia, industry, and government. Chemical Engineering Communications publishes full-length research articles dealing with completed research projects on subjects such as experimentation (both techniques and data) and new theoretical models. Critical review papers reporting on the current state of the art in topical areas of chemical engineering are also welcome; submission of these is strongly encouraged.
