摘要：The indium-bearing zinc ferrite (IBZF) was synthesid, ud as a rearch object, and mechanically activated with the planetary ball mill. Sulphur dioxide was introduced as reductant and leachant to create a reducing atmosphere and react with water to provide H + . The reductive leaching kinetics of activated IBZF samples was studied with sulphur dioxide as leachant and reductant. The results showed
that the mechanical activation could change the physicochemical properties of IBZF significantly, thus improving its reactivity. The unreacted shrinking core model was an excellent fit for the kinetics of zinc and indium leaching. This indicated that the leaching process was controlled by surface chemical reaction and the activation energy was 62.57 and 57.30?kJ·mol ?1 . After the mechanical activation for 60?min, the activation
