摘　　要：安徽某金矿浮选尾矿中金的品位为1.28 g/t,浮选尾矿中的金损失较为严重.为了查明其原因,作者采用MLA等大型先进的仪器对其浮选尾矿中金的赋存状态进行了深入研究.结果表明,本矿石中金主要为自然金,而且主要为包裹金;其主要共生矿物为黄铁矿、闪锌矿及毒砂.颗粒金分布在5~10μm,5μm以下粒级的银矿物颗粒占比20.17%.因此对于浮选富集来看,需要进一步磨矿,提高单体解离度.The flotation tailings of a gold mine in Anhui Province contain a grade of 1.28 g/t of gold, and the gold loss in the flotation tailings is very serious.MLA and other large-scale advanced instruments were applied to conduct an in-depth study of the gold deposit in the flotation tailings.The results show that the main gold in the ore is natural gold, and the main gold in the deposit is gold. The main symbiotic minerals are pyrite,sphalerite and arsenopyrite. particle gold was distributed within the range of 5~10 μm.silver mineral particles smaller than 5 μm accounted for 20.17 %. From the perspective of flotation enrichment, mineral particles need to be further grinded to improve monomer dissociation.
