内蒙古某难选钨矿石选矿工艺研究

摘要

A refractory tungsten ore from Inner Mongolia was sorted by the process of preclassification-gravity separation-flotation .The results show that under the appropriate conditions ,tungsten grade in tungsten concentrate is 66 .52% and tungsten recovery is 57 .31% by gravity separation ,and tungsten grade in tungsten concentrate is 65 .89% ,and tungsten recovery is 16 .75% by flotation .The total recovery of tungsten is 74 .06% .%针对内蒙古某难选钨矿石 ,研究了采用预先分级—浮选—重选联合工艺流程分选钨精矿.试验结果表明 :在适宜条件下 ,重选钨精矿品位为66 .52% ,重选钨回收率为57 .31% ;浮选钨精矿品位为65 .89% ,浮选钨回收率为16 .75% ;钨总回收率为74 .06% .矿石分选效果较好.
