Abstract
The primary metal minerals of an Ag -Pb-Zn polymetallic ore in Nei Monggol are gale-na, sphalerite and pyrite .The gangue minerals such as sericite , muscovite, chlorite, kaolin, clay, are easy to be muddy in the grinding process and interfere with flotation .According to the ore prop-erties, the depressant MP which has an obvious effect on easy floating and mudding gangue and high selective collectors were used , and flotation tests were studied , The results showed: in the case of the raw ore containing Pb 1.95%, Zn 1.97%and Ag 100.50 g/t, finally the lead concen-trates containing Pb 50.08%, Ag2 040 .35 g/t with recovery of Pb 91.62%, Ag 72.34%, and zinc concentrates containing Zn 46.81%with recovery of Zn 82.04%were achieved through a se-lective flotation process , and the paper provides the reference basis for studying the same type of Ag-Pb-Zn ore.关键词
