The presence of valuable metals in the iron ore and tailings, makes the beneficiation of those tailings attractive; on the other hand due to the important effects of sulfur content in iron ore on the technical problems and environmental issues in steel making, a tank leaching process at atmospheric conditions was performed for the desulfurization of the iron ore and also for the extraction of valuable metals from iron ore tailings.A central composite design (CCD) was conducted as a response surface methodology for the optimization and evaluation of the leaching process effective parameters. The results obtained showed that more than 75% of total sulfur was removed and simultaneously more than 50% of the valuable metals (Ni, Co, Cu, Mo) were extracted by the chemical leaching under optimized condition. Also, the conversion of sulfide bearing minerals into useful by-products, phosphorus removal and executing the process under atmospheric conditions are the other advantages of the proposed method.
