| Abstract: |
| Gold-bearing sulphur concentrate in one mine was dealt with cyanide leaching process.The influence of some factors including ore fineness、sodium cyanide dosage and extraction time on the leaching rate of gold were examined.The results showed that the best leaching rate of 42.12% could be obtained using cyanide leaching directly under the condition of grinding fineness -38μm 90.65%,the NaCN dosage 5kg/t and extraction time 24h.The leaching rate of gold could be improved by 13 percent with 800g/t lead nitrate added at the best cyaniding condition. |
