According to the different types of ilmenite minerals, the beneficiation process of ilmenite is generally divided into the following types.

152, ilmenite-magnetite dressing, because ilmenite in the ore often infects magnetite and nonmetallic minerals in the form of independent inclusions, the principle of treating this kind of ore is to discard the tailings as coarse as possible, and then carry out grinding and magnetic separation on ilmenite concentrate. When sulfide exists, sulfide concentrate is floated first, and then fine ilmenite is floated.

6442, hematite-ilmenite mineral processing, usually in this kind of ore hematite and ilmenite are closely * * *, mineral processing can only choose titanium-iron mixed concentrate from it, and then get pig iron and high titanium slag by pyrometallurgy.

05. In the mineral processing of perovskite-type titanomagnetite, generally, titanomagnetite is selected by wet low-intensity magnetic separation first, then calcite is floated by fatty acid collectors, and ilmenite is floated after middling is stripped.

98, ilmenite beneficiation process depends on the nature of the material. Because the specific gravity of titanium minerals is greater than that of nonmetallic gangue minerals, gravity separation can be used as pretreatment or roughing tailings. Magnetic separation is widely used to remove iron to improve the concentrate grade of ilmenite, and can also be used to enrich ilmenite with a small proportion of gangue minerals. Electrostatic separation is mostly used for the purification of titanium concentrate selected by other processes when it contains various non-conductive minerals; Flotation is more suitable for the beneficiation of primary ilmenite fine ore.

Through the beneficiation test, the beneficiation process of ilmenite was determined, and then the ilmenite magnetic separator was tailored according to the production capacity, which ensured the beneficiation effect.
