钒钛铁精矿金属化球团是转底炉煤基直接还原钒钛铁精矿后的产品,其中含有铁、钒、钛等多元素。采用实验室湿式磁选机对钒钛铁精矿金属化球团进行了磁选的可行性研究,通过正交试验考察了电流强度、粒度、矿液比等参数对金属化球团中铁、钛回收率的影响。结果表明:在电流强度2.5 A,粒度-74μm(-200目),矿液比为1∶7时,铁、钛的回收率分别为90%和45%。
Vanadium-titanium-iron concentrate metallized pellets are the products of direct reduction of vanadium-titanium-iron concentrates from coal-based rotary bases, which contain many elements such as iron, vanadium and titanium. Feasibility study on magnetic separation of vanadium-titanium-iron concentrate metallized pellets was conducted by laboratory wet magnetic separator. The effects of current intensity, particle size and mineral-liquid ratio on the magnetic properties of iron, titanium Effect of recovery rate. The results showed that the recoveries of iron and titanium were 90% and 45% at the current density of 2.5 A, the particle size of -74 μm (-200 mesh) and the ratio of mineral to liquid of 1: 7.
