新疆某金矿矿石载金矿物与脉石矿物之间嵌布关系复杂，围岩蚀变强烈，含泥量大，泥化现象严重，对载金矿物的浮选影响较大。针对该矿石的特点，通过配合使用捕收剂Y89－0、异戊基黄药和Z－105，以及采用泥砂分选工艺，获得了良好的技术指标，金回收率得到显著提高。原矿金品位为3．43 g／t时，闭路试验可获得金回收率90．86％、金品位42．40 g／t的金精矿。
The complex association relationship between gold-carrier minerals and gangue minerals ,strong altera-tion of gangue minerals and high content of gangue slime have strong influence on the flotations of a gold ore in Xin -jiang.The experimental results show that gold recovery can be improved significantly when the process of mud and sand separation is used along with the use of Y 89-0,isoamyl-xanthate and Z-105 as combined collector .A gold concen-trate with the recovery of 90.86 % Au and the grade of 42.40 g/t Au can be produced from the feed with the Au grade of 3.43 g/t by the closed-circuit test.
