Abstract: Lead, which is an indispensable and important metal in the development of mining industry chain, has become increasingly important status in the national economic construction.As the lead resource consumption continually, lead sulfide resources cannot meet the demand of national economy.The efficient use of lead oxide minerals becomes an important way for supplement lead mineral resources.This paper briefly introduces the current research in the flotation of lead oxide mineral at home and abroad, which mainly includes reagent system and technological flowsheet of flotation, and makes the relevant technical prospects for technological flowsheet of flotation, so as to provide reference for practice and theory.
