某含铜铁矿石中铜的品位为0.31%，因含铜矿物嵌布复杂，浮选分离铜困难。采用新型捕收剂DY-1对该矿进行选矿试验研究，通过一次粗选、二次精选和一次扫选中矿顺序返回的闭路试验流程可获得铜精矿品位15.67%，回收率56.85%的较好指标。
某含銅鐵礦石中銅的品位為0.31%，因含銅礦物嵌佈複雜，浮選分離銅睏難。採用新型捕收劑DY-1對該礦進行選礦試驗研究，通過一次粗選、二次精選和一次掃選中礦順序返迴的閉路試驗流程可穫得銅精礦品位15.67%，迴收率56.85%的較好指標。

For a copper-bearing iron ore with copper grade of 0.3 1%,due to the complex disseminated relationship of its copper-bearing minerals,this ore characteristic brings much trouble in separating copper by flotation.A mineral processing test is conducted by adopting a new collector DY-1 and better indicators with copper concentrate grade of 1 5.6 7% and recovery of 56.85% are obtained through the closed-circuit test flow in the sequence of one roughing,two cleaning and one middling-scavenging.
