阐述了中国难处理金矿石的主要概况,介绍了难处理金矿石常用的预处理方法,包括超细磨、焙烧、加压氧化、生物氧化等技术,以及金矿石的联合回收工艺,包括重选—浸出联合工艺、重选—浮选联合工艺、浮选—浸出联合工艺,并分析了各种预处理方法及联合回收工艺的特点,同时结合当前难处理金矿石选矿工艺现状,提出存在的主要问题,并在此基础上对其未来的相关研究作出展望.
The paper overviewed refractory gold ores in China,introduced common pre-treatment methods of refractory gold ores,including ultra-fine grinding,roasting,pressure oxidation and bio-oxidation,and combined gold recovery processes including gravity-leaching,gravity-flotation,flotation-leaching,analyzed the characteristics of the pre-treatment and combined recovery processes,put forward major problems of these processes taking into consideration the current status of refractory gold ore treatment processes,and based on it,made prospect about related research in the future.
