Comprehensive Utilization of Ilmenite Tailings

Ilmenite tailings are the waste residues generated after ilmenite ore beneficiation, mainly including iron, titanium, and other elements. To achieve comprehensive utilization of ilmenite tailings, several approaches can be adopted:

1. Magnetic separation: Magnetic separation can be used to separate the magnetic minerals from the ilmenite tailings. This can help to recover iron and other magnetic minerals from the tailings.

2. Gravity separation: Gravity separation techniques can be used to separate the heavy minerals from the ilmenite tailings. This can help to recover titanium and other heavy minerals from the tailings.

3. Flotation: Flotation is a separation technique that can be used to recover minerals from the ilmenite tailings. It can be used to recover titanium, iron, and other minerals from the tailings.

4. Chemical leaching: Chemical leaching can be used to extract valuable metals from the ilmenite tailings. This technique involves the use of chemicals to dissolve the metals from the tailings.

5. Thermal treatment: Thermal treatment can be used to convert the ilmenite tailings into useful products. For example, the tailings can be used as a source of raw material for the production of cement or construction materials.

In summary, ilmenite tailings can be comprehensively utilized through various techniques such as magnetic separation, gravity separation, flotation, chemical leaching, and thermal treatment. These approaches can help to recover valuable minerals and metals from the tailings and reduce waste and environmental pollution.
