缅甸某锡矿脱硫选锡试验研究
|
摘要
缅甸某含硫锡矿有用矿物嵌布粒度细,主要有价元素为锡和硫,其中,锡含量为2.94%、硫含量为9.65%。试验采用先脱硫后选锡的浮选工艺流程,实现了硫和锡的高效回收。结果表明,在其他条件最佳的情况下,使用新型活化剂X-45(ZL201010124710.7)、KT-51 (ZL201610148276.3)活化硫和锡,最终得到硫精矿的品位和回收率分别为36.68%和94.02%,锡精矿的品位和回收率分别为21.06%和60.27%。该研究可为该类含硫锡矿资源的有效开发利用提供技术支撑。
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 provide technical support for the effective exploitation and utilization of this kind of sulphurbearing tin ore resources.
