| Abstract: |
| Aiming at the problems of high leaching gold grade and low rate of gold leaching of a skarn-type gold ore in Gansu, this paper provides an access to the study of gold leaching rate of 91.08-92.16%, with the approach of comparing the experimental data of 3.70g/t of the gold by pre-oxidation, leaching while grinding, leaching aid and by oxygen extraction. The experimental research provides a significant reference for the research of cyanide leaching of gold. |
