摘　　要：难处理金矿直接氰化金的回收率低,为了提高回收率,必须采取一定的方法进行处理。本文简要地分析了难处理金矿的难浸原因,介绍了目前常用的处理难处理金矿的方法,详细地介绍了非氰化法、强化氰化、预处理法、火法熔炼法处理难处理金矿的研究方法和研究进展。介绍了各种方法的优缺点及应用现状和前景。The directly cyanide leaching rate of refractory gold ores is very low. Certain methods for processing must be taken to increase the recovery rate. The reason of low leaching rate of refractory gold ores was briefly analyzed, and several common research methods and research progress of refractory gold ores, such as non-cyanidation, strengthening cyanidation, pretreatment method, pyrometallurgical smelting, were introduced herein. Advantages and disadvantages of various methods, application status and prospects were also introduced.
