Pretreatment of refractory gold ores and current research status and progress of intensified cyanidation process

In the paper,overview and classification of refractory gold ores were given,and the reason that they are hard to leach was briefly analyzed.The pretreatment method commonly used and the intensified cyanidation for the re-fractory gold ores were comprehensively introduced,including biological oxidation,chemical oxidation,magnetic pulse, coverage control method,competitive adsorption and so on.And the basic mechanism,the advantages and disadvanta-ges of each method,their application status and progress at home and abroad were thoroughly introduced.The prospects and trends of cyanide leaching of refractory gold ores were discussed based on that.
