某石煤型钒矿选矿新工艺研究

摘要

The beneficiation test combined magnetic‐flotation process was carried out in order to solve the problem in the stone coal (in Jiangxi province) containing roscoelite and roscoelite limonite with magnetic properties .The high effective depressant GZS and amine collector TAN were used in flotation to recycle the vanadium .The result shows that the stone coal containing 0 .86% V2 O5 was increased to 1 .41% with the recovery of 84 .01% ,and the process discard 50 .80% gangue of the raw ore ,w hich greatly reduced the cost of production and improved the utilization efficiency of vanadium resources .%针对江西某石煤型钒矿中的钒主要赋存于钒云母、含钒云母及褐铁矿中，且部分含钒矿物具有弱磁性的特点，采用磁－浮联合工艺，浮选中使用高效抑制剂抑制GZS及胺类捕收剂TAN回收钒．在给矿钒品位为0．86％的条件下，获得钒品位1．41％、回收率84．01％的钒精矿，为冶金提钒预先抛弃了50．80％的脉石矿物，大大降低了生产成本，有效地提高了钒资源的利用率．
