真空冶金回收废旧锌锰电池的汞和镉试验研究
Experimental research on recycling of Hg and Cd from waste zinc-manganic batteries by vacuum metallurgy
摘要
Abstract
A vacuum metallurgical process for treating waste zinc-rnanganic batteries and recovering mercury (Hg) and cadmium (Cd) elements was studied.The effect of vacuum degree, temperature and heating time on Hg and Cd removal was investigated.The experimental results show that vacuum metallurgical process can effectively recover Hg / Cd in waste batteries and its recovering rate increases with the increase of temperature and heating time.When the vacuum degree is 91.99-98.66 kPa, the heating time is 2.5 h; when the temperatures are 350 ℃ for Hg and 725 ℃ for Cd, the recovering rate is up to 95%.关键词
