摘　　要：随着黄金需求量的不断增长,高品位易处理的金矿资源越来越少,高硫富砷难处理金矿资源已成为国内黄金生产的重要原料。高硫富砷难处理金矿是世界上公认的最难处理的金矿资源之一,也是储量最大、可回收价值最高的难处理金矿之一。综述了近年来高硫富砷难处理金矿焙烧预处理技术的研究进展,详细介绍了传统焙烧、固化焙烧、双层球团焙烧、微波焙烧等预处理技术的原理和效果及其优缺点,并展望了焙烧氧化法的发展方向。With the ever increasing demand for gold,high-grade and easy-to-handle gold ore resources are on the decrease.Thus the refractory gold ore containing high-sulfur and arsenic has to be an important raw material for domestic gold production.As one of the most difficult-to-handle golden resources in the world,the refractory golden deposit containing high-sulfur and arsenic minerals presents the largest reserves and the highest valuables to be reco-vered.The research and development on calcination pretreatment technology for refractory gold ores with high sulfur and arsenic content in recent years was reviewed.The principle,effects,advantages and disadvantages of the pretreatment technologies such as traditional roasting,fixing roasting,double-layered pellet roasting and microwave roasting were introduced in details.The research interests on calcination-oxidation method were expected.
