摘要
综述了一些比较典型的难浸金矿的预处理技术及其工艺方法,预处理方法主要有焙烧法预处理、生物氧化预处理、富氧或加助浸剂预处理、碱浸预处理、微波加热预处理等。难处理金矿将成为我国黄金工业发展的主要资源,因此难浸金矿的处理及预处理技术的开发与研究是当前我国黄金工业提金的关键。
The treatment of refractory gold ore become increasingly important in gold industry of China.In this paper,the pre-treatment technologies used for refractory gold ores were reviewed.These methods include roasting.biological oxidation,using oxygen-enriched air with additives,alkali leaching,microwave heating,etc.
