钒钛磁铁矿精矿提铁降硫工艺试验研究

针对攀枝花钒钛磁铁矿精矿性质进行弱磁选提铁和精矿反浮选降硫等条件试验,在此基础上进行流程试验研究。结果表明:该磁铁矿弱磁选可获得铁品位57.17%,铁回收率89.94%的铁精矿;该铁精矿通过反浮选降硫使含硫降至0.26%,最终获得优质的钒钛磁铁矿精矿。

Experimental Study on Iron Improvement and Desulphurization of a Vanadium-titanium Magnetite Concentrate

In view of the properties of vanadium-titanium magnetite concentrate from Panzhihua, some condition tests for iron improvement and desulphurization of reverse flotation were made. Based on this, the open-circuit flow-sheet tests were carried out. The tests results show that Fe concentrate grading at 57.17% with an 89.94% recovery was achieved through the low-intensity magnetic separation. Then S content in concentrate can be lowered to 0.26% by reverse flotation desulphurization flow-sheet, with high-grade magnetite concentrate finally achieved.
