| 中文摘要: |
| 某金矿生物选矿采用重选+浮选流程进行。生物重选试验表明,金精矿回收率从常规重选的55.9%提高到65.3%。重选尾矿生物浮选时,对常规浮选试剂丁基黄药做了补加生物试剂,或部分替换,以及全部替换试验。实验室上述试验结果证明,生物选矿对金矿是可行的,并具无污染、安全、降低成本的应用前景。 |
| 英文摘要: |
| In a gold mine biological beneficiation is adopted and recovery of native gold increases to 65.3% from 55.9% of the traditional gravity beneficiation. During biological floatation of the gravity-beneficiated tailing some biological reagent was added to substitute for butyl-xanthate and only biological reagent added to replace the butyl-xanthate. The result shows that biological beneficiation is feasible to gold ore with safety,low cost and without pollution. |
