摘要
甘肃某细粒浸染型金矿石中金主要以包裹金形态存在,且载金矿物黄铁矿与脉石矿物连生关系复杂。针对该矿石的性质,进行了选矿试验研究。其结果表明:在最佳试验条件下,采用阶段磨矿-阶段浮选工艺,可获得金品位30.17 g/t、金回收率81.23%的较好指标;硫精矿经氧化焙烧—氰化浸出,金对原矿的回收率为6.96%,金总回收率达88.19%。
Mineral processing test was carried out for a fine grain disseminated gold ore from Gansu Province. The gold-carrying mineral is pyrite and it is connected with gangue minerals in a complex way. The test results under optimal test conditions,a stage grinding- stage flotation process can obtain a gold grade of 30. 17 g / t and a gold recovery rate of 81. 23 %. Sulfur concentrates go through roasting- cyanide leaching process,the recovery of primary gold ores is 6. 96 % and the total recovery rate of gold is 88. 19 %.
