Due to high oxidation rate of a lead-zinc sulfide ore, the on-site flotation practice presented poor beneficiation indices. In view of this problem, an optimized closed-circuit process consisting of two stages of roughing, two stages of scavenging, one stage of rough cleaning of combined roughing concentrates, two stages of cleaning and two stages of scavenging for roughing concentrates was proposed. With slime (800 g/t) and CD-2 (300 g/t) as pyrite depressants, CD-1 (600 g/t) and water glass (600 g/t) as gangue depressants, sodium sulfide (500 g/t) as a sulfiding agent, copper sulfate (500 g/t) as an activator, butyl xanthate (200 g/t) as a collector, and terpineol oil (21 g/t) as a foaming agent, a closed-circuit flotation test produced a bulk concentrate grading 16.25% Pb and 27.69% Zn with a lead recovery of 65.05% and a zinc recovery of 92.49%. Compared with the previous on-site flowsheet, the Pb grade and Pb recovery are improved by 2.24 percentage points and 9.36 percentage points, while Zn grade and Zn recovery up by 1.57 percentage points and 5.14 percentage points respectively.
