| The directly cyanide leaching rate of refractory gold ores is very low. Certain methods for processing must be taken to increase the recovery rate. The reason of low leaching rate of refractory gold ores was briefly analyzed, and several common research methods and research progress of refractory gold ores, such as non-cyanidation, strengthening cyanidation, pretreatment method, pyrometallurgical smelting, were introduced herein. Advantages and disadvantages of various methods, application status and prospects were also introduced. |
