摘要:
某铜锌多金属硫化矿石含铜0.38 %、锌1.69 %、硫12.48 %，铜、锌、硫为主要有价回收元素。为实现铜、锌、硫的有效分离回收，开展了选矿工艺流程及药剂制度试验研究。结果表明：采用铜锌硫顺序优先浮选工艺，即优先选铜、再选锌、最后选硫工艺，在Z-200作为选铜捕收剂，硫酸锌和亚硫酸钠组合作为锌抑制剂，石灰作为硫抑制剂，乙基黄药和丁基黄药作为选锌捕收剂的条件下，闭路试验获得了铜精矿铜品位21.95 %、铜回收率80.52 %，锌精矿锌品位45.29 %、锌回收率83.22 %，硫精矿硫品位49.79 %、硫回收率85.02 %的试验指标。

Abstract:
A copper-zinc polymetallic sulfide ore contains 0.38 % copper,1.69 % zinc,and 12.48 % sulfur,of which copper,zinc,and sulfur are the main valuable elements for recovery.To achieve effective separation and recovery of copper,zinc,and sulfur,experimental research on the ore-dressing process and reagent regime was carried out.The results showed that using a copper-zinc-sulfur preferential flotation process,that is,separating copper first,then zinc,and finally sulfur,with Z-200 as the copper collector,zinc sulfate and sodium sulfite combination as the zinc depressant,lime as the sulfur depressant,and ethyl xanthate and butyl xanthate as the zinc collector,closed-circuit experiments obtained a copper grade of copper concentrates of 21.95 %,a copper recovery rate of 80.52 %;a zinc grade of zinc concentrates of 45.29 %,a zinc recovery rate of 83.22 %;and a sulfur grade of sulfur concentrates of 49.79 % and a sulfur recovery rate of 85.02 % for experimental indicators.
