摘　　要：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%。The metallized pellet of vanadium-bearing titaniferous iron ore concentrate containing iron, va- nadium, titanium and other elements is the product of coal-based direct reduction of the concentrate in ro- tary hearth furnace. By using laboratory wet magnetic separator, a new technology of magnetite separation of iron and titanium from metallized pellet was introduced, and its feasibility was also studied by experi- ments. The effects of current intensity, particle size and ore to liquid ratio on the recovery rate of iron and titanium were examined through orthogonal experiment. The experimental results show that the recovery rates of iron and titanium are 90% and 45% respectively with the current intensity of 2.5 A, particle size of - 74 μm and ore to liquid ratio of 1：7 .
