| 摘 要： | 贵州省某金矿含砷、锑金矿石，金粒度特细，有害元素含量多，金的赋存状态又十分复杂。通过在粗造作业采取强化措施后，使该矿石中的微细粒包裹金得到了较好地回收。尾矿金的损失由常规浮选的２ｇ／ｔ降至０．５ｇ／ｔ，金的回收率由７０％提高到９１％以上，浮选效果得到明显改善。

| Abstract: | Containing arsenic,antimony and a large amount of harmful elements, the gold ore in a certain sold mine of Guizhou Province is extra refractory, due to its extra fine-gold-grain and complicated gold occurrence. Through intensified measures adopted,the fine-grained and encapsulated sold in the ore were well-recovered, the loss of sold in tailing reduced from 28/t in conventional flotation to 0.5g/t and gold recovery raised from 70% to over 91 %.This showed that the flotation effect was markedly improved. |
