Experimental Study on Magnetite Separation of Iron and Titanium from Metallized Pellet of Vanadium-bearing Titaniferous Iron Ore Concentrate

The metallized pellet of vanadium-bearing titaniferous iron ore concentrate containing iron,vanadium,titanium and other elements is the product of coal-based direct reduction of the concentrate in rotary 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 experiments. 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.
