锡石多金属硫化矿再磨再选流程的优化

Optimization of cassiterite polymetallic sulfide ore regrinding process

针对车河选矿厂所处理锡石多金属硫化矿的"重选-浮选-重选"工艺流程前重中矿尾矿再磨工艺中未能做到粗细分磨和贫富分磨,经过试验研究与现场应用,将整个流程锡回收率提高4个百分点。

For the problems of Che He Ore Dressing Plant concentrator processed cassiterite multi-metal sulfide ore about "gravity beneficiation-floating-gravity beneficiation" process, which is the first gravity beneficiation tailings re-grinding process failed to achieve fine separation grinding and separdte grinding of the rich and the poor, through experimental research and field application study, the results showed that the throughout process of recovery of tin increased by 4 percentage points.
