| Abstract: |
| Sphalerite and galena are the primary recoverable minerals in a lead-zinc ore in Yunnan. The grade of zinc and lead are 5.64% and 0.92% respectively. Through systemic process mineralogy study, it is found that the oxidation degree of the ore is high and the grain size distribution of sphalerite and galena are all fine. The results show that these two reasons are the main factors influencing floatation indexes of the ore. |
