Abstract
Extraction of lead from sulfide concentrates by hydrometallurgical routes is a potentially attractive method.In this paper,the extensive studies on hydrometallurgy of processing lead concentrates are introduced and the various methods are properly reviewed.Emphasis of the paper is placed on investigation of chloride hydrometallurgy of lead,which includes direct electrolysis of lead concentrates,ferric chloride leaching of lead concentrate,recovery of lead from an intermediate product lead chloride and treatment of complex sulphides.
