摘要
原矿中钼品位为0.081%,铜含量很低为0.04%,而硫含量较高为2.70%,钼铜硫矿物之间以及它们与脉石矿物之间嵌布粒度微细,并且铜硫之间及与其他硫化矿物之间呈微细粒互相包裹,脉石矿物异常好浮。为了同时回收该矿石中的目的矿物,研究采用了合理有效的选矿流程方案及药剂制度,使难选铜、钼、硫矿物得到有效的回收,获得钼精矿品位46.10%、回收率83.43%,铜精矿品位11.92%、回收率74.40%,硫精矿品位45.35%、回收率90.51%的良好选矿指标。
In this paper mineral of Mo, Cu, S and gangue embed size minutein in crude ore, but between Mo, Cu, S and other sulphur ore minute parcel each other, and flotaty of gangue was better, degree of Mo 0.081%, degree of Cu was lower auout 0.04%, degree of S was higtter auout 2.70%.In order to recover Mo, Cu, S at the same time the reasonable effective flotation process flowsheet and medicament were adopted to obtain better index:concentrate of Mo degree was 46.10% and recovery was 83.43%; concentrate of Cu degree was 11.92% and recovery was 74.40%; concentrate of S degree was 45.35% and recovery was 90.51%.
