| Abstract: |
| Working principle of high pressure grinding roll was introduced. Proportion of fine part was substantially increased after high pressure grinding roll. Cyanidation leaching results show that compared with conventional crushing has no advantages in all-slime cyanidation process with gold leaching rate dropping from 89.90% to 79.88%, but gold leaching rate in heap leaching process rises from 53.85% to 79.88% after high pressure grinding roll compared with conventional crushing. |
