摘　　要：含砷金矿是典型的难处理金矿资源,也是我国金矿资源的重要组成部分。介绍了焙烧氧化、细菌氧化、浮选分离、非氰浸出等工艺,并评述了各工艺的优缺点及其适用性,在此基础上总结了含砷金矿提金工艺的发展方向和研究重点。Gold ores containing arsenic is a typical refractory gold resource. It is also one of the important gold types in our country. A few processes of the extracting technology was reviewed, including roasting oxidation process, bacterial oxidation process, flotation separation process, non-cyanide leaching process and so on. The advantages and disadvantages of each technology and its application were also discussed. The development direction and research focus were summarized.
