 abstract={Cadmium-bearing zinc ferrite (CBZF) is an unavoidable product in zinc smelting industry during the roasting stage for high cadmium-containing zinc concentrate. In this work, the influences of temperature, initial sulfuric acid concentration and partial pressure of sulfur dioxide on cadmium leaching were investigated. The results showed that an increase of temperature, sulfuric acid concentration and partial pressure of sulfur dioxide significantly enhanced the cadmium leaching efficiency. The maximum leaching efficiency of cadmium reached 99.2% at the temperature of 85°C, the initial sulfuric acid concentration of 80 g/L and the partial pressure of sulfur dioxide of 200 kPa. H+ played a key role during the reductive decomposition process of CBZF. The probable reaction mechanisms and the diagrammatic sketch were presented.},
