摘要
胶东某矿业公司矿石中金以细粒包裹金为主,泥质矿物含量较高。多年来,金的回收率较低。针对矿石性质,进行了磨矿细度(粗选尾矿再磨)、改善药剂制度等试验研究与生产实践,金的回收率提高了3.63%,企业每年可增加经济效益300余万元。
The gold mineral is mainly fine particle packed gold in a gold mine of Shandong,meanwhile the argillaceous mineral content is high.The recovery rate is relatively low in the past years.Aiming at the properties of the ore,the rough floatation tailings is regrinded and the reagent system is improved.The gold recovery rate is enhanced by 3.63 % and additional 3 million RMB benefit per year is obtained.
