Abstract: Theoretical analysis of the selectively leaching cadmium from waste Ni-Cd battery was carried out. The relationship between the separation results and the leaching conditions was experimentally investigated. The results show that on the condition of the 1:5 ratio of solid and liquid, at room temperature and pH value 2 of the H2SO4 solution in 2 h leaching, the leaching ratios of cadmium and nickel are 100% and 6.5% respectively.
