Characterized by fine dissemination size and high slime content, a refractory lead?zinc sulfide?oxide mixed ore from Guangdong was processed by adopting a Pb/Zn differential flotation flowsheet, which consists of sulfurization?dithiophosphate method to recover lead minerals, sulfurization?xanthate method to recover zinc minerals, and a combination of water glass and sodium hexametaphosphate used to depress gangues. The closed?circuit batch test with such flowsheet yielded a lead concentrate grade of 47.16% Pb, 5.35% Zn and 363.25 g/t Ag with recoveries of 69.28% Pb, 58.91%Ag, as well as a zinc concentrate approaching 46.54% Zn grade at recovery of 85.52%.
