The composition of the waste water in hydrometallurgy is complicated, and after neutralization and settle, there are small amount element of heavy metal surpassed the set standard.Since the waste water contents too big amount of salt such as SO4-、 CL-, it can not be discharged.For this reason, the treatment with the waste water from high concentration hydrometallurgy becomes the major environmental protection problem placed before nonferrous metal metallurgy companies.This paper aims at exploring the most effective ways on the basis of practical need to save energy and deal with the waste water of hydrometallurgy.
