Current Situations of Refractory Gold Ore′s Pretreatment Method Research and Its Tendency |
| |
| Abstract: | The definition of refractory gold ore and its types were given. Reasons why it is hard to leach out rerfactory gold ore were briefly analyzed. Pretreatment by oxidation method can give good results. The current situations of industrial application and research on pretreatment methods which include roasting oxidation, pressure oxidation, bacteria oxidation and chemical oxidation for refractory gold ores at home and abroad were summarized. In addition, the advantages and disadvantages of each method were reviewed. The prospects and trends of their development were also discussed. |
