| Abstract: | It showed from the study of the feature of the refractory gold concentrate of a certain mine and the study of gold extraction by bacterial preoxidation technology that this gold concentrate was low arsenic and low sulfur fine grained inclusion refractory gold concentrate,of which the direct cyanide leaching rate was only 35.3%.After 5 days'bacterial pre oxidation,the cyanide leachning rate of gold reached 92.5%. |
