| Abstract: | The lead-sulfur concentrates with high content of arsenic from Hebei Province was taken for exploring the lead-arsenic separation technique. The lead-sulfur rougher concentrates, after being re-ground, were beneficiated by using lime and sodium humate as arsenic depressants. A closed-circuit flotation flowsheet with one stage of roughing, two stages of scavenging and three stages of cleaning was adopted, resulting in the lead concentrate grading 76.12% Pb at 94.89% recovery, and an arsenic-sulfur concentrate grading 11.89% As at 90.35% recovery. It is shown that efficient lead-arsenic separation can be realized. |
