摘　　要：含砷难处理金精矿直接氰化浸出无法取得良好的经济技术指标,需在浸出前对其进行预处理。本文介绍了3种含砷难处理金精矿的预处理工艺,包括氧化焙烧法、热压氧化法、生物氧化法,简要阐述了各工艺的作用机理、研究进展及优缺点,为含砷难处理金精矿预处理提供参考。The direct cyanidation leaching of refractory gold concentrate arsenic-containing cannot obtain good economic and technical indicators,so it is necessary to pre-treat it before leaching.In this paper,three pretreatment processes for arsenic-containing refractory gold concentrates are introduced,including oxidation-roasting,heat pressure oxidation and biological oxidation.The mechanism,research progress,advantages and disadvantages of each process are briefly expounded,which provide reference for the pretreatment of arsenic-containing refractory gold concentrates.
