摘　　要：为提高金浸出率,难处理金矿进行氰化浸出前需进行预处理,目前预处理方法主要有氧化焙烧、加压氧化、细菌氧化、化学氧化及磁脉冲法等,应根据矿石性质选取适宜的预处理方法。Pretreatment technology should conducted on refractory gold ore to increase its leaching rate. Pretreatment technologies for the refractory gold ore were introduced by oxidation calcinations,high pressure oxidation,bacterial oxidation,chemical oxidation,magnetic pulse method.
