C 2 2药剂在铅浮选回路和锌浮选回路中可作为黄药的部分替代品。用ВЭДК药剂时 ,银从锌精矿转移到铜铅精矿中 ,它可部分代替黄药。ДМП药剂对金和银具有很强的捕收能力 ,所以可作为黄药的辅助捕收剂。在含银铅锌矿石浮选时 ,铅精矿铅品位从 67 4%提高到 71 4% ,银的品位从 70 8 8g/t提高到 82 3 3 g/t。铅的回收率提高 2 4% ,银回收率提高 9 4%。在硫化矿浮选中 ,用C 2 1药剂部分代替氰化钠 ,不仅减少了氰化钠的用量 ,而且降低了黄药的用量 ,铅回收率提高 1 9% ,锌回收率提高 3 1% ,同时精矿质量得到改善。
C 2 2 agents can be used as partial substitutes for xanthate in lead flotation circuits and zinc flotation circuits. With ВЭДК agents, silver is transferred from zinc concentrates to copper-lead concentrate, which partially replaces xanthate. ДМП Pharmacy has a strong ability to collect gold and silver, so it can be used as an auxiliary collector of xanthate. During the flotation of silver-bearing lead-zinc ore, the lead grade of lead concentrate increased from 67.4% to 71.4% and the grade of silver increased from 70.88g / t to 82.33g / t. Lead recovery increased by 24% and silver recovery by 94%. In the flotation of sulphide ore, partial replacement of sodium cyanide with C 2 1 agent not only reduced the dosage of sodium cyanide, but also reduced the dosage of xanthate, the recovery rate of lead increased by 19% and the recovery rate of zinc increased by 31% , While the quality of concentrate has been improved.
