| Abstract: |
| Based on the process mineralogy research, beneficiation tests were carried out on a lead-zn-silver polymetallic ore containing arsenic in Yunnan, which contains 2.93% lead, 2.80% zinc, 110.45g/t silver, 26.94% sulfur and 0.53% harmful element arsenic. A process composed of lead priority? zinc-sulfur bulk flotation and reseparation process was adopted, combined with BK915, an efficient lead-silver collector, and BD, a pyrite inhibitor. As a result,the experiment produced a lead concentrate with lead grade of 68.46%, lead recovery of 88.50%, silver grade of 2358 g/t, silver recovery of 84.37% and arsenic grade of 1.45% ,a zinc concentrate with zinc grade of 51.32%, zinc recovery of 89.07% and arsenic grade of 0.18%;a Sulfur concentrate with 49.14% sulfur grade and 82.35% sulfur recovery. |
