| Abstract: | Refractory gold ore was defined,and the reasons for their intractable and their corresponding countermeasures were outlined.The pre-treatment methods before leaching gold by cyanide such as oxidation roasting,hot oxidation,biological oxidation,chemical oxidation were reviewed and compared.The non-cyanide leaching agents such as halogen,thiourea,thiosulfate,etc.,and their mechanism of dipping gold and the advantages and disadvantages were commentated. |
