Extend Progress in Research on Lead Electrowinning in the Process of Lead Hydrometallurgy

Owing to the requirements of environmental protection and restricted by lead resources,great attention has been paid to the lead hydrometallurgy in recent years.Moreover,the process of lead electrowinning is one of the key technologies for realizing lead hydrometallurgical process.This paper introfuced the development status of the lead electrowinning technology,and compared and analyzed some important technological parametres of lead electrowinning in the systems of chloride salt,fluorboric acid and fluorsilicic acid.
