摘　　要：我国金矿资源储量丰富,但难处理金矿比重较大,含金黄铁矿作为最主要的载金矿物,其中的金赋存状态复杂、伴生矿物种类繁多,导致开采和选冶困难。金在黄铁矿中的赋存状态可分为裂隙金、间隙金、表面吸附金、包裹金和晶格金。基于此,分别介绍了重选、浮选、化学浸出、生物处理等选别工艺的研究现状。China has abundant gold reserves,which includs large proportion of refractory gold ore.Pyrite is one of the most important gold bearing ores,in which the gold occurrence state is complex and the associated minerals are various,which makes it difficult to exploit and extract.The occurrence of gold in pyrite can be divided into fracture gold,interstitial gold,surface adsorption gold,inclusion gold and lattice gold.On the basis of occurrence state,the research progress of gravity separation,flotation,chemical leaching and biological treatment are introduced.
