Improvement of Cyanidation of Antimonial Refractory Gold/Silver Ores .
WEBUltrafine grinding process prior to cyanidation could be, therefore, used as a physical pretreatment method to improve the cyanide leaching of gold and silver from the antimonial refractory ore. It can be also concluded from this study that the development of a suitable chemical pretreatment method is required to overcome the refractoriness of ...
