甘肃东海金矿矿石浮选试验研究

Experimental study on gold ore floatation in Gansu Donghai gold mine

甘肃东海金矿矿石采用堆浸工艺处理,金回收率仅为50%,银回收率为58%。为提高金、银回收率,根据该矿石性质,进行了浮选工艺回收金试验。浮选闭路试验结果表明,金的回收率达到87.13%,银的回收率达到90.23%。

With heap leaching process, the gold recovery rate is only 50% and silver recovery is 58% in Donghai gold mine. In order to enhance the recovery rate, flotation tests are carried out based on the properties of the ore. In the closed-circuit floatation test, the gold recovery rate is 87.13% and that of silver is 90.23%.
