| Abstract: | In this paper,the leaching conditions of sediment of copper and cadmium,such as particulate size,tempera-ture,input concentration of H 2 SO 4 and stir velocity were researched.When the leaching conditions were changed,which greatly affected the each metallic element's leaching velocity and ratio of recovery.The optimum conditions were obtained.On the choosed conditions of technics,the total leaching ratio of Zn,Cd and Cu was98.5%. |
