| Abstract: | A vacuum metallurgical process for treating waste zinc-manganic batteries and recovering mercury(Hg) and cadmium(Cd) elements was studied,and the impact of vacuum degree,temperature and heating time on Hg and Cd removal was investigated.The experimental results demonstrated that vacuum metallurgical process could effectively recover Hg/Cd in waste batteries and its recovering rate increased with the rising of temperature and heating time.The optimum conditions of recovering Hg/Cd were obtained as follows: v... |
