摘要
西藏某金矿,金主要赋存于含砷黄铁矿及毒砂中。矿石为粉砂质泥岩,其碎屑泥质成分高,浮选效果差,且不能直接浸出。通过对该矿选矿产品进行金、硫、砷相关系列分析,确定该矿属卡林型金矿。针对该金矿选矿试验研究,最终采用重选富集—氧化焙烧—浸出工艺,获得了较好的选矿技术指标。
In agold mine of Tibet, gold mainly exists in arsenic pyrite and arsenopyrite. The ores belong to silty mudstone, with high component of shaly clay, which leads to poor flotation effect and inaccessibility of direct leaching. Though serial analysis of the ore with regard to gold, sulfur and arsenic, we conclude that the mine is a Carlin-type gold deposit. In the mineral processing test, a gravity separation enrichment-roasting-leaching processing technique achieves best beneficiation indices and is finally adopted.
