摘要
本文综述和评论了近年来文献中所报导的难浸金矿石的处理方法。难浸金矿石的直接浸出包括加压氰化,炭浸和非氰化浸出法;在传统氰化浸出之前进行的预处理过程包括焙烧,化学氧化和生物氧化。对各种处理方法的发展状况,适应性及可行性给予了必要的讨论。
This paper gives a review of the various methods of treating refractory gold ores reported in various literatures. Direct leaching of refractory gold ores consists of pressure cyanidation CIL and cyanide-free leaching.The pre-treatment of them before conventional cyanide leaching includes roast, chemical oxidation and biological oxidation. Besides, the advance,adaptability and feasibility of the various treatment methods are discussed in this paper.
