Abstract：For the separation problems such as using cyanide and low recovery of lead and zinc in
a lead-antimony-zinc polymetallic sulfide mine，the cyanide-free flotation process was studied. The
results indicated that the beneficiation index of lead，antimony and zinc could be effectivelyimproved by the combination of new collector CSU11 and dithiophosphate 25. In the closed-circuit
tests，lead-antimony concentrate containing % Pb，% Sb and % Zn could be obtained
through using the principal flowsheet of magnetic-flotation and the sequential preferential flotation
of lead-antimony-zinc，wi
