| 摘 要： | 新疆某金矿氰化尾渣含Cu0.29%、Pb0.27%、Zn0.66%、Au0.65t/g、Ag6.2t/g,铅锌氧化较严重而难于回收,铜为主要回收对象,进行了药剂制度和浮选条件的探索试验研究。在一粗一扫二精的条件下,选用Na2SO3+ZnSO4为锌硫矿物的抑制剂、PAC为铜矿物捕收剂,获得了铜品位15.27%、铜回收率80.55%,铜精矿中金品位8.32g/t,回收率23.46%;银品位129g/t,回收率37.69%的指标,实现了尾渣中铜矿物的综合回收。

| Abstract: | The cyanide tailings of a gold ore in Xinjiang contains Cu0.29%,Pb0.27%,Zn0.66%,Au0.65t/g and Ag6.2t/g.It is difficult to recover lead and zinc for their serious oxidation.The copper is the main object to recover.The reagent system and the flotation condition were explored.When the flowsheet of one roughing,one scavenging and two cleaning was adopted,using Na2SO3+ZnSO4 as depressant for zinc and sulfide and PAC as collector for copper,the copper grade of 15.27%and the recovery of 80.55%,the gold grade of 8.32g/t and the recovery of 23.46%and the silver grade of 129g/t and the recovery of 37.69%were obtained,realizing the comprehensive recovery of copper in the tailings. |
