摘要：
In this paper, three different processes-chelation accompanied by oxidation, oxidation followed by chelation, and oxidative acid leaching followed by chelation-are designed for extraction of zinc from oxide-sulphide zinc ore, and through a comparison of the redox potentials, suitable oxidation additives are determined for each process. Besides, effects of oxidant additives doping level on zinc recovery are investigated. The results show that the zinc leaching degree can reach 83.72% with addition of NaO being 0.3 mol/L in the process of chelation accompanied by oxidation, the zinc leaching degree can reach 92.40% with NaO adding 0.5 mol/L in the process of oxidation followed by chelation, and the zinc leaching degree can reach 93.02% under a condition of NaClO doping level being 0.1 mol/L in the process of oxidative acid leaching followed by chelation. All three processes prove their value on extraction of oxide-sulphide zinc ores.
