自1887年J.MacArfher和R·Forrest发明氰化法从矿石中提金并于1890年美国Mecrur金矿第一个成功地把该工艺用于工业生产中以来,氰化法已成为世界各国从脉金矿中提金的标准方法。该工艺因具有高达96％的金回收率,流程简易及很好的经济效益而一直沿用至今,尚没有被别的提金工艺所取代。但是除氰化物为剧毒因而环境保护要求极其严格外,影响该工艺的应用主要是金及其基质的矿物因素。诸如金矿物、金矿石的粒级分布(特别是
Since 1887, when J. MacArfher and R. Forrest invented the cyanidation method to extract gold from ores and the first successful application of the process to industrial production by the Mecrur gold mine in the United States in 1890, the cyanidation method has become the worldwide Pulse gold gold standard method. The process has been in use ever since, with up to 96% gold recovery, streamlined process and good economic efficiency, and has not been replaced by other gold extraction process. However, in addition to cyanide is highly toxic and thus environmental protection requirements are extremely strict, the application of the impact of the process is mainly the gold and its matrix mineral factors. Such as gold minerals, gold ore size distribution (especially
