Some main results of testing research were as fellows : i. in the course of testing of leaching zinc dross, leaching zinc dross by sulfuric acid was researched and the effects on the leaching rate of the zinc dross were analyzed by author, the optimum conditions of leaching testing of zinc dross were determined as fellows : liquid - solid ratio 6 : 1, stirring ratio 250r / min, granularity 120 mesh, the soaking time 5h, the concentration of sulfuric acid of 30 %, and under these conditions, the rate of leaching zinc is above 92. 0 %. ii. in the course of testing of purification, on the basis of comprehending and comparing all present methods of the manganese - removal and iron - removal, the oxidizing method of manganese - removal in zinc sulfate solution using ammonium persulfate was put forward and the oxidizing method of iron - removal in zinc sulfate solution using the goethite process and oxidation - hydrolysis process was adopted
