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。In a gold mine biological bene 3% from 55.9% of the traditional gravity ciated tailing some biological reagent was gent added to replace the butyl-xanthate. ore with safety, low cost and without poll iciation is adopted and recovery of native gold increases to 65. beneficiation.
