AbstractAs important rare raw material, Se and its compounds are widely used in metallurgy, glass manufacturing, chemicals and pigments, and electronics industry. However, current processes used for Se recovery are usually constrained by the serious pollution and high energy consumption. To dispose the issues in the process of Se recovery, this study developed an environmentally friendly process by using MnO2 in dilute H2SO4 as oxidant to efficiently recover Se and Cu. The effects of MnO2 dosage, H2SO4 concentrations, stirring speeds and temperature on the recovery were investigated. It was found that the major Se bearing phases in anode slime were elemental Se and Ag2Se. The oxidation capacity of MnO2 greatly increased with the H2SO4 concentration higher than 0.5 M and at a temperature above 60 degrees C. Optimum conditions derived from this study were 1.2 g MnO2 dosage, 1.0 M H2SO4, 600 rpm, and temperature at 80 degrees C, under which both the Se and Cu were recovered by 100% after 6 h. The cost-benefit analysis of the proposed process manifested that the profit of processing 1 t of anode slime was $ 82, and the sensitivity analysis showed that the price of Cu2Se and the Se recovery rate were the most important determinants of the profit. This research has great potential in Se recovery from anode slime. (C) 2018 Elsevier Ltd. All rights reserved.
