摘要:
甘肃某金矿矿石金质量分数为4.3×10-6,锑、砷和碳依次为0.48%、0.37%和1.84%,属于典型的复杂难处理锑金矿,现场生产采用“重选—浮选—浮尾氰化”工艺回收金和锑。由于矿石中金嵌布粒度粗细不均,锑、砷和碳等杂质含量高,导致金总回收率仅为82%,金损失严重。为提高金回收率,采用电子探针对浮选尾矿中金的赋存状态进行了研究,在此基础上开展了提高金回收率的试验研究。试验结果表明:浮选尾矿中部分金以晶格金或包裹金形式赋存于毒砂、黄铁矿和辉锑矿等硫化矿物中,氰化浸出过程中难以与浸出液接触,是导致金损失过高的主要原因;氰化浸出前先对浮选尾矿进行分级,分级后对 +0.038 mm粗粒级进行再磨和活化浮选,强化对包裹金和晶格金的回收,然后再将粗粒浮选尾矿与-0.038 mm细粒级合并进行氰化浸出,金总回收率可提高约9个百分点,尾渣中金质量分数降低至0.3×10-6以下。
