| 摘 要： | 某金矿原矿金品位为1.94g/t,金元素主要赋存于自然金中,金属矿物以黄铁矿为主,脉石矿物主要为长石、石英等。现场原有工艺生产精矿金品位为45.20g/t,金回收率为87.31%。使用组合捕收剂异戊基黄药+BK903G对其进行试验研究,在55%-0.074mm的磨矿细度条件下,通过一粗、两精、两扫的选别流程,获得精矿金品位为82.86g/t,金回收率为93.19%。此外,使用尼尔森选矿机,进行重-浮联合流程试验探索,同样获得较好指标。

| Abstract: | The run-of-mine ore of gold is 1.94g/t, the gold mainly occurrence in native gold. Pyrite is the main metal ore. The gangue minerals mainly consist of quartz and feldspar. The original concentrate with the gold grade of 45.20g/t and the gold recovery of 87.31% were produced. In this paper, a combined collector agent of iso-amyl xanthate and BK903G was used to replace the old one. By the circuit of one rougher, two cleaners and two scavengers, finally a concentrate with the gold grade of 82.86g/t and the gold recovery of 91.45% were produced. Using the Nelson concentrator, the gravity - flotation process were tested, we can gain a better indicator also. |
