摘要
对湖北省某地含砷、含硫微细粒金矿采用阶段磨矿—强化分散矿泥—活化载金矿物等浮选措施,提高了金精矿富集比,金品位从5.46g/t提高到34.4g/t,回收率为83.55%。
At present, it is found that the microfine-grained gold ore containing arsenic and sulfur can not recycle by cyanide process directly, and the refractory gold, a difficulty for greater exploitation efficiency is urgently needed to solve. This kind of gold ore, in Hubei, is studied to improve enrichment ratio of gold concentrate, by adopting several different flotation measures, including stages grinding, strengthened dispersion of slime and gold bearing mineral activation. Finally, the gold grade rise to 34.4 g/t from 5.46 g/t with 83.55% gold recovery.
