| Abstract: |
| A sulphide-bearing tin ore in Myanmar has a finer disseminated grain size, the main valuable elements being tin and sulfur. Among them, tin content is 2.94% and sulphur content is 9.65%.The process of pre-desulfurization and floating tin was adopted to realize the efficient recovery of sulfur and tin.The results show that, when other conditions are optimal, new activators X-45(ZL201010124710.7）and KT-51（ZL201610148276.3）are used to activate sulfur and tin, and finally, sulfur concentrate grade and recovery were 36.68% and 94.02%, tin concentrate grade and recovery were 21.06% and 60.27%. The research can provides technical support for the effective exploitation and utilization of this kind of sulphur-bearing tin ore resources. |
