摘要
因氧化严重,印尼进口某多金属矿铜硫分离困难,铁精矿含硫严重超标.针对该矿矿石性质,开发了浮选-磁选联合工艺,浮选中以HT药剂消除溶液中Cu2+,实现了铜硫矿的分离和回收,浮选尾矿再用磁选回收铁,获得铜精矿产率9.75%,品位22.05%,回收率75.17%,含金0.97 g/t,含银14 g/t.硫精矿产率30.76%,品位49.94%,回收率64.23%.铁精矿产率26.84%,品位60.24%,回收率76.26%.
Owing to serious oxidation, the copper-sulphur separation of the polymetallic ore from Indonesia is difficult to recover. Targeting the nature of the ore, the flotation and magnetic separation process is exploited.HT agent is used to eliminate Cu^2＋in flotation to separate and recover the cooper-sulfide ore. Iron is recovered by magnetic separation from the flotation tailings. A copper concentrate yield is 9.75 %, and a copper grade of22.05 % with a copper recovery of 75.17 %, which contains gold 0.97 g/t, silver 14 g/t. A sulfur concentrate yield is 30.76 %, a sulfur grade of 49.94 % with a sulfur recovery of 64.23 %. An iron concentrate yield is26.84 %, an iron grade of 60.24 % with an iron recovery of 76.26 %.
