We put zinc sulphide mine into different sulphate system and analyzed polarization curve about anodic oxidation.we found that the mine was oxidized effectively and the rapid oxidation happened when we adopted the zinc sulphide ore suspension electrolyte which contained ZnSO_4,(NH_4)_2SO_4 and H_2SO_4. This system was suffice to product metal zinc industrially. The appropriate suspension electrolyte composition consisted of zinc 90～130g/l,(NH_4)_2SO_430～50g/l, H_2SO_430～50g/l, suspension electrolysis temperature 50℃, anodic oxidation potentiometer 0.6～0.8V.
