Titanium ore beneficiation technology

Titanium ore beneficiation technology

Titanium ore is an important metal ore commonly used in the production of titanium alloys, titanium dioxide, and other products. However, due to the complexity of its mineral composition, the beneficiation of titanium ore is difficult. This article will introduce the titanium ore beneficiation technology and its operating steps.

1、 Mineral composition of titanium ore

The main minerals of titanium ore include Ilmenite, titanium Magnetite, ilmenite, etc. Among them, Ilmenite is the most common one, its chemical formula is FeTiO3, with high iron content but low titanium content. The chemical formula of titanium Magnetite is Fe3O4, with high titanium content but low iron content. The chemical formula of titanium vanadium ore is FeTiO3-V2O5, with high titanium and vanadium content.

2、 Titanium ore beneficiation technology

Titanium ore beneficiation technology mainly includes methods such as gravity separation, magnetic separation, flotation, etc. Among them, gravity separation is mainly used to separate Ilmenite with high iron content; Magnetic separation is mainly used to separate titanium Magnetite with high titanium content; Flotation is mainly used to separate titanium vanadium ores with high titanium and vanadium contents.

1. Reselection

Gravity separation is a method of separation by using mineral density difference. Firstly, the titanium ore is crushed to a certain particle size, and then placed in a gravity separator for sorting. Ilmenite can be separated by gravity concentration because of its high density and fast settling speed.

2. Magnetic separation

Magnetic separation is a method of separating minerals by utilizing their magnetic differences. Firstly, the titanium ore is crushed to a certain particle size, and then placed in a magnetic separator for sorting. As titanium Magnetite has strong magnetism, it can be separated by magnetic separation.

3. Flotation

Flotation is a method of separation that utilizes differences in mineral surface properties. Firstly, the titanium ore is crushed to a certain particle size, and then a flotation agent is added for flotation. Flotation agents can create a certain degree of hydrophilicity on the surface of titanium vanadium ore, thereby enabling it to interact with water and achieve separation.

3、 Operating Steps

1. Grinding of titanium ore

Firstly, the titanium ore needs to be crushed to a certain particle size, which is generally required to be less than 0.5mm. Equipment such as jaw crushers and cone crushers can be used for crushing.

2. Reselection

Place the crushed titanium ore into a gravity separator for sorting. Gravity separators usually use equipment such as flotation machines or centrifuges.

3. Magnetic separation

Place the crushed titanium ore into a magnetic separator for sorting. Magnetic separators usually use equipment such as high-strength magnetic separators or wet magnetic separators.

4. Flotation

Add the crushed titanium ore to a flotation agent for flotation. The flotation agent is usually hexadecyl trimethyl Ammonium bromide and other organic substances.

IV. Summary

Titanium ore beneficiation technology is a complex process that requires multiple methods for separation. Gravity separation, magnetic separation, flotation and other methods have their own advantages and disadvantages, and they need to be selected based on the mineral composition and beneficiation requirements of the ore. In practical operation, attention needs to be paid to issues such as ore crushing and selection of flotation agents to ensure the beneficiation effect.
