| 中文摘要: |
| 对吉林某金矿进行了重选、无毒浸出和浮选3种选矿工艺对比实验，研究了磨矿细度、药剂用量、矿浆浓度等因素对选矿效率的影响。结果表明，无毒浸出工艺回收率为76.13%，重选工艺基本无优先选别作用；采用浮选工艺，在磨矿细度为-0.074 mm含量为90.52%，捕收剂异戊基黄药与丁铵黑药的药剂用量均为60 g/t，矿浆浓度为45%，活化剂硫酸铜用量为400 g/t条件下，对金品位为3.31 g/t的原矿进行一粗一精二扫闭路实验，最终获得品位为42.34 g/t，回收率为86.76%的金精矿，回收效果最好。 |
| 英文摘要: |
| Comparative experiments of gravity separation, non-toxic leaching and flotation were carried out for a gold mine in Jilin province, and the effects of grinding fineness, reagent dosage and pulp concentration on beneficiation efficiency were studied. The results showed that the recovery rate of non-toxic leaching process was only 76.13%, and that the gravity separation process has no preferential separation function. Under the conditions: -0.074 mm of grinding fineness with 90.52% content, 60 g/t dosage of both collector isoamyl xanthate and ammonium butyrate black agent, 45% of pulp concentration, 400 g/t dosage of activator copper sulfate, one roughing one refining two scavenging closed-circuit experiment was carried out on the raw ore with gold grade of 3.31 g/t, and the final gold concentrate was 42.34 g/t. The recovery rate of gold was 86.76%, and the recycling effect was the best. |
