Outline
A kind of polymetallic lead-zinc sulfide ore in Guangxi was taken for experimental research. In view of its characteristics of high zinc and low lead, as well as difficulty in the separation between zinc and lead, a new type of efficient inhibitor JFR-1 was adopted in the experiment. It is shown that the lead-zinc sulfide ore was subjected to a lead-zinc bulk flotation, consisting of one roughing, two cleaning and two scavenging, followed by a separation of lead and zinc, consisting of one roughing, two cleaning and two scavenging, finally resulting in a lead concentrate grading 21.00% pb at 72.82% recovery, a zinc sulfide ore grading 6.96% Zn at 94.21% recovery, and a tailings grading 0.04% Pb and 0.13% Zn with a lead recovery of 10.85% and a zinc recovery of 4.79%. Thus, the enrichment and separation of lead and zinc can be actualized.
