Description

Technical Field

[0001] The invention relates to the technical field of ilmenite production, and in particular to a magnetic separation device for ilmenite. Background Art

[0002] Ilmenite is a weakly magnetic mineral, and its specific magnetic susceptibility and density are higher than those of gangue minerals. For minerals of the same particle size, it has a much larger volume magnetization intensity than gangue minerals. In this way, during magnetic separation under a certain field strength, gangue minerals and a part of fine iron-containing silicate minerals in ilmenite are easily thrown into tailings. Strong magnetic separation can effectively separate ilmenite from gangue minerals, so as to achieve the purpose of enriching titanium metal and processing ilmenite that is difficult to enrich by gravity separation. It is often used in the process of concentration and tailings. Magnetic separation equipment is needed for magnetic separation of ilmenite.

[0003] At present, when the magnetic separation device is used, the ilmenite is generally directly transported by a conveyor belt, and then the ilmenite is separated and magnetically separated by an L-shaped plate with a permanent magnet in the magnetic separation component. The gangue minerals are discharged from the tailings outlet along the conveyor belt, and the ilmenite concentrate is adsorbed to the corner of the L-shaped plate and discharged from the ilmenite outlet. In this way, since the ilmenite transported on the conveyor belt is relatively concentrated, when the ilmenite is magnetically separated by the permanent magnet in the magnetic separation component, it is easy to be adsorbed and discharged in time; at the same time, the ilmenite concentrate adsorbed to the corner of the L-shaped plate is prone to residual accumulation, which affects the adsorption effect of the subsequent magnetic separation of the ilmenite concentrate and reduces the quality of the magnetic separation of the ilmenite. Now there is an urgent need for a magnetic separation device for ilmenite to solve the above problems. Summary of the invention
