摘要
对我国黄金资源的基本情况及各种难浸金矿石预处理工艺的现状进行了综述。分析了焙烧氧化、加压氧化、生物氧化、化学氧化、微波加热等预处理工艺的特点,指出微波预处理具有加热均匀,能耗低等优点,是一种很有发展前途的难浸金矿石预处理方法。
The gold resources in China and present status of pretreatment process of various refractory gold ores are reviewed. Analysis is made of the characteristics of the pretreatment technologies such as roasting oxidization,pressure oxidization, bio-oxidization, chemical oxidization and microwave heating. It is pointed out that the microwave pretreatment, characterized by uniform heating and low energy Consumption, is a very promising pretreatment method for refractory gold ores.
