镇沅金矿250t/d选厂尾矿再回收金试验研究

Experimetn on Recovery of Gold from Tailings of the 250 t/d Mill of Zhenyuan Gold Mines

针对镇沅金矿250t/d选厂金回收率不高等问题对现有生产尾矿进行了再选研究。结果表明，通过再选粗精矿再磨可提高5％－6％的生产回收率。

In the light of problems such as poor gold recovery at the 250 t/d mill of Zhenyuan Cold mines,experiments have been undertaken to retreat the existing tailings from this mill.The experimental results show that gold recovery at the mill may be raised with an increment form 5 to 6% by regrinding the rougher con centrate form the tailings reflotation.
