| 中文摘要: |
| 采用响应曲面法(RSM)对贵州某金矿浮选过程中的磨矿细度、pH值、捕收剂用量对金品位和回收率的影响进行了研究。结果表明磨矿细度对金品位和回收率的影响最大，为显著影响因素。根据预测的结果，采用磨矿细度(-200目占比)70%、pH值8.44、捕收剂用量144 g/t的最优条件，以“一粗两精一扫”的闭路试验流程，最后得到了金品位为29.94 g/t，金回收率为95.14%的金精矿。 |
| 英文摘要: |
| The effects of grinding fineness, pH and collector dosage on gold grade and recovery in the flotation process of a gold mine in Guizhou were studied by a response surface method (RSM). The results showed that the grinding fineness has the greatest influence on gold grade and recovery, which is a significant factor. According to the predicted results, the optimal conditions of 70% grinding fineness (-200 mesh proportion), pH value of 8.44 and 144 g/t of collector dosage, and the closed-circuit test process of "one coarse, two fine and one sweep" were adopted, the gold concentrate with 29.94 g/t of gold and 95.14% of gold recovery was finally obtained. |
