| 摘 要： | 铜硫矿中低品位伴生金由于难富集到计价品位而常被忽略回收。针对含铜1.84%、含硫11.09%、含金0.12×10-6的低金高硫铜矿石,采用P10作为选铜金捕收剂,H2SO4作为选硫活化剂,丁黄作为选硫捕收剂,在低碱条件下,闭路试验可获得含铜20.98%、铜回收率为86.23%,含金1.2×10-6、金回收率为74.80%的铜金精矿及硫品位为48.9%、硫回收率为74.47%的合格硫精矿,实现了铜、硫、金的高效综合回收。低碱度铜硫分离工艺使活化剂用量大为减少,有利于硫的综合回收,降低了选矿成本。

| Abstract: | The low-grade associated gold in copper ore is often overlooked to recover,due to its difficult to enrich to valuation grade.According to the low gold high-sulfur copper ore,which contains 1.84% of Cu,11.09% of S,and 0.12×10-6of Au,P10 is taken as collector for copper and gold,sulfuric acid as activator and butylxanthate as collector for sulfur.A closed-circuit flotation test was conducted at a low alkalinity,which a copper concentrate are produced with content of 20.98% Cu with a recovery of 86.23% and 1.2×10-6Au with a recovery of 74.80%,and sulfur concentrate of 48.9% S with a recovery of 74.47%.Therefore,a comprehensive and efficient recovery of copper,sulfur and gold can be realized.Low alkali separation technology of copper-sulfur,which greatly reduced the amount of activator,is conducive to comprehensive recovery of sulfur and lower processing costs. |
