摘要:
本次试验研究对象为柿竹园萤石精矿.原矿含CaF295.5%,Sn0.059%,WO30.13%.为了回收萤石精矿中的钨,对原矿进行粒度分析后,采用新型选矿设备—悬振锥面选矿机进行试验研究.通过试验研究,确定了设备的最佳进行参数,经过一次粗选,可获得品位10.56%,回收率32.23%的钨精矿,钨品位富集了81倍,而萤石精矿选钨后,萤石品味提高了2.8个百分点.试验结果证明,悬振锥面选矿机对柿竹园萤石精矿再选钨有良好的回收效果.
Abstract:
The object of this research is fluorite concentrate in Shizhuyuan.The raw ore assays CaF2 95.5%,Sn 0.059%,WO3 0.13%.To recover the tungsten from fluorite concentrate,after particle size studies,using a new type of mineral processing equipment-the hang-vibrate of cone concentrator.The best operating parameters were determined by condition tests,after a roughing,the grade and the recovery of tungsten concentrates at10.56% and 32.23%,tungsten grade enrichment of 81 times,and after recovering the tungsten from fluorite concentrate,the grade of fluorite increased by 2.8%.The results demonstrate that HVC concentrator is favorable for re-concentration recovery of tungsten from fluorite concentrate in Shizhuyuan.
