| 中文摘要: |
| 采用正交试验的方法对甘肃某金矿浮选过程中粗选作业的磨矿细度、2#油用量、黄药用量、硫化钠用量以及硫酸铜用量对回收率的影响进行了研究。结果表明，2#油用量和硫化钠用量为影响金回收率的显著因素。粗选最优条件为:磨矿细度为-74 μm含量为55%、2#油用量为14 g/t、黄药用量为28 g/t、硫化钠用量为100 g/t、硫酸铜用量为15 g/t。在此条件下，经一粗一精两扫的闭路试验，可得到回收率为89.87%，品位为42.0 g/t的金精矿。 |

| The influence of grinding fineness, the amount of 2# oil, the amount of xanthate, the amount of sodium sulfide and the amount of copper sulfate on the flotation recovery rate of a gold ore in Gansu were investigated by orthogonal experiment method. The results showed that the amount of 2# oil and the amount of sodium sulfide were significant factors affecting the recovery of gold. The optimal conditions for roughing were: grinding fineness of -74 μm content accounted for 55%, 2# oil of 14 g/t, xanthate of 28 g/t, sodium sulfide of 100 g/t and copper sulfate of 15 g/t. The recovery rate of gold concentration was 89.87% and the grade was 42.0 g/t under the optimal conditions. |
