摘　　要：某金矿随着开采深度的增加,矿石性质发生变化,为高效开发利用深部矿石,对该矿石进行了系统的选矿试验研究,探索了单一浮选、重选及重选—浮选联合工艺。结果表明:该金矿石可选性较好,单一浮选工艺指标较好,磨矿-分级后采用一次粗选、三次扫选、两次精选流程,获得了金品位62.15 g/t、金回收率95.44%,银品位150.61 g/t、银回收率74.71%的金精矿。With increasing mining depth in a gold mine,the ore property has changed.In order to efficiently develop and utilize ores from deep in the mine,systematic beneficiation experiment on the ore is carried out,which explores single flotation,gravity separation and gravity separation-flotation joint process.The results show that the gold ores have good recoverability with good single flotation index,and the grinding-classification prior to once rough-ing,three times scavenging and twice cleaning obtains the gold concentrates with gold grade 62.15 g/t,gold recovery rate 95.44%,silver grade 150.61 g/t,silver recovery rate 74.71%.
