摘　　要：针对难处理金矿石进行了定义,简述了其难处理的原因及其相应对策。对氰化浸金前的焙烧氧化、热压氧化、生物氧化、化学氧化等预处理方法进行了综述,并就其相互的优缺点进行了比较;同时也对非氰浸金剂如卤素、硫脲、硫代硫酸盐等,以及它们的浸金机理和优缺点进行了评述。Refractory gold ore was defined,and the reasons for their intractable and their corresponding countermeasures were outlined.The pre-treatment methods before leaching gold by cyanide such as oxidation roasting,hot oxidation,biological oxidation,chemical oxidation were reviewed and compared.The non-cyanide leaching agents such as halogen,thiourea,thiosulfate,etc.,and their mechanism of dipping gold and the advantages and disadvantages were commentated.
