magnetic separation of ilmenite

1) Magnetic separation + flotation combined method. In ilmenite dressing, it is always a difficult problem to recover the fine particle size. In mineral processing, flotation method can only to a certain extent to achieve the recovery of less than 0.02 mm of granular ilmenite, but there will be a lot of quartz and other gangue in the concentrate after flotation, which seriously affects the quality of flotation. Therefore, the …

    Dec 01, 2002 · Magnetic separation of roasted ilmenite The roasted ilmenite was separated using the Frantz Isodynamic Separator. Two electric current settings were applied in the separator, 0.15 and 0.3 A, and the corresponding magnetic field intensity was 0.12 and 0.24 T. The separation results are presented in Fig. 5, Fig. 6, Fig. 7, Fig. 8

    However, most of the previous researchers, using a roasting step, did not seem to be able to separate the Fe-bearing titanium minerals (ilmenite and leucoxene) from the Fe-free titanium minerals (rutile and anatase). An investigation was therefore carried out to study the changes in magnetic properties after roasting to the types of minerals contained in the oil sands tailings

    Ilmenite is the titanium-iron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steel-gray solid. Altered ilmenite forms the mineral leucoxene, an important source of titanium in heavy mineral sands ore deposits. Leucoxene is a typical component of altered gabbro and diorite and is generally indicative of ilmenite in the unaltered rock
