| Abstract: |
| The grade of gold of the ore is 5.20g/t. In order to know the gold occurrence, the systemic research is carried out with instrument such as microscope and MLA. The result shows that about 91.22% Au occurring in Gold, and about 8.37% Au occurring in Calaverite, Bessmertnovite, Petzite and Hessite. Because these Au-Ag telluride minerals are hard to be leached, the Au occurring in them is also hard to be leached with cyanide. |
