Titanium ore gravity separation method

Titanium ore gravity separation method

Titanium ore is an important metal ore widely used in fields such as aerospace, shipbuilding, automotive, electronics, and chemical engineering. However, in the mining and beneficiation process of titanium ore, due to the complex nature of the ore, it is difficult to separate and extract, which brings great difficulties to production. Therefore, studying the method of titanium ore gravity separation is of great significance for improving the utilization rate of titanium ore and reducing production costs.

1、 Properties and beneficiation principles of titanium ore

The main component of titanium ore is titanium dioxide, which usually contains impurities such as iron, aluminum, vanadium, manganese, magnesium, etc. Due to the existence of these impurities, the ore is complex in nature and difficult to separate and extract. Therefore, the main principle of titanium ore beneficiation is to utilize the physical and chemical properties of the ore for separation and extraction.

2、 Titanium ore gravity separation method

1. Gravity beneficiation method

Gravity beneficiation is a method of separation by using the density difference of mineral particles. The density of titanium ore is 4.2-4.3g/cm ³， The density of impurity elements is generally small, so they can be separated by gravity beneficiation. Gravity beneficiation method includes heavy medium beneficiation, centrifugal beneficiation, vibration beneficiation, and other methods.

2. Magnetic separation method

Magnetic separation is a method of separating minerals by utilizing their magnetic differences. Ferromagnetic impurity elements contained in titanium ore can be separated by magnetic separation. The magnetic separation method includes two methods: dry magnetic separation and wet magnetic separation.

3. Flotation method

Flotation method is a method of separating minerals by utilizing their differences in hydrophilicity and hydrophobicity. The impurities such as silicate and Aluminate contained in titanium ore can be separated by flotation. Flotation methods include direct flotation, reverse flotation, and integrated flotation with coarse and fine flotation.

3、 Advantages and disadvantages of titanium ore gravity separation method

1. Gravity beneficiation method

Advantages: Simple equipment, low cost, suitable for large-scale production.

Disadvantages: The separation effect is limited by the difference in mineral density, and it is difficult to separate minerals with similar density.

2. Magnetic separation method

Advantages: Good sorting effect, can effectively separate titanium ore containing ferromagnetic impurities.

Disadvantages: The equipment is complex, the cost is high, and the requirements for mineral particle size, magnetism, etc. are high.

3. Flotation method

Advantages: good separation effect, suitable for titanium ore containing impurities such as silicate and Aluminate.

Disadvantages: Complex equipment, high cost, and high requirements for mineral particle size and flotation agent types.

4、 Conclusion

The titanium ore gravity separation method is an important means to improve the utilization rate of titanium ore and reduce production costs. Gravity beneficiation, magnetic separation, flotation and other methods have their own advantages and disadvantages, and suitable methods should be selected for titanium ore beneficiation based on specific circumstances. In the future, with the continuous progress of technology, titanium ore gravity separation technology will continue to improve, providing better support for the mining and utilization of titanium ore.
