Ilmenite is an important metal ore, which has a broad application prospect. However, the mining and utilization of Ilmenite has always been a difficult problem, because its beneficiation is very difficult. This paper will introduce Ilmenite beneficiation technology to solve this problem for everyone.
1、 Characteristics of Ilmenite
Ilmenite is an ore containing titanium and iron, usually black or brown. It is mainly composed of Titanate minerals, including Ilmenite, Ilmenite, ilmenite, titanium Magnetite, etc. The titanium content of Ilmenite is generally 30%~60%, and the iron content is 30%~50%.
Ilmenite is characterized by high hardness, high density, strong magnetism, good chemical stability, good thermal stability, good corrosion resistance, etc. These characteristics make Ilmenite have a broad application prospect in aviation, aerospace, military industry, chemical industry, electronics and other fields.
II. Beneficiation principle of Ilmenite
The beneficiation principle of Ilmenite is to separate titanium, iron and other useful components from Ilmenite by physical and chemical methods, so as to improve the grade and recovery rate of Ilmenite.
The beneficiation process of Ilmenite includes grinding, flotation, magnetic separation and gravity separation. Among them, grinding is the process of grinding Ilmenite to a certain size, flotation is to use the affinity difference between Ilmenite and water to make it surface under the action of bubbles, magnetic separation is to use the magnetic difference of Ilmenite to separate it, and gravity separation is to use gravity to separate Ilmenite.

1. Grinding technology
grinding is an important step in the beneficiation process of Ilmenite, which determines the subsequent beneficiation effect. The key to grinding technology is to choose appropriate grinding equipment and grinding media to achieve the best grinding effect.
At present, commonly used grinding equipment includes ball mills, rod mills, AG mills, etc. Grinding media include steel balls, steel rods, ceramic balls, etc. Different grinding equipment and media have different grinding effects on Ilmenite, which needs to be selected according to the actual situation.
2. Flotation technology
flotation is an important step in the beneficiation process of Ilmenite, which determines the recovery rate and grade of Ilmenite. The key to flotation technology is to choose appropriate reagents and flotation models to achieve the best flotation effect.
At present, commonly used reagents include collectors, foaming agents, regulators, etc. Different reagents have different flotation effects on Ilmenite, which needs to be selected according to the actual situation. The commonly used flotation machines include mechanical flotation machines, air flotation machines, centrifugal flotation machines, etc. Different flotation machines have different flotation effects on Ilmenite, which needs to be selected according to the actual situation.
3. Magnetic separation technology
Magnetic separation is an important step in the beneficiation process of Ilmenite, which can separate iron and other impurities from Ilmenite and improve the grade of Ilmenite. The key to magnetic separation technology is to choose the appropriate magnetic separation model and magnetic field strength to achieve the best magnetic separation effect.
At present, commonly used magnetic separation models include wet magnetic separators, dry magnetic separators, etc. Different magnetic separators have different magnetic separation effects on Ilmenite, which needs to be selected according to the actual situation. The magnetic field strength is also a key factor affecting the magnetic separation effect, and needs to be adjusted according to the actual situation.
4. Re-selection technology
Gravity concentration is an important step in the beneficiation process of Ilmenite, which can separate the light impurities in Ilmenite and improve the grade of Ilmenite. The key to reselection technology is to select appropriate reselection equipment and media to achieve the best reselection effect.
At present, commonly used gravity separation equipment includes gravity concentrators, centrifugal concentrators, etc. Different gravity separation equipment has different gravity separation effects on Ilmenite, which needs to be selected according to the actual situation. The re selected medium includes water, heavy medium, etc. Different gravity separation media have different gravity separation effects on Ilmenite, which needs to be selected according to the actual situation.
4、 Conclusion
Beneficiation technology of Ilmenite is a complex work, which requires comprehensive application of grinding, flotation, magnetic separation, gravity separation and other technical means. In actual production, it is necessary to select appropriate beneficiation technology and equipment according to the characteristics and beneficiation requirements of Ilmenite to achieve the best beneficiation effect.
