| Abstract: |
| The study shows that the metallurgical performances of gold flotation depend on the distribution of gold minerals in pyrite and gangues, disseminated grain size of pyrite and size of gold minerals in gangues. Also, the oxidation of ore, changing pyrite into limonite, have an effect on gold flotation. The liberation degrees of gold minerals and pyrite affects gold recovery. At normal cyaniding, the finer the gold concentrate is ground, the lower gold content of leaching residue. |
