Mineral processing methods for coastal titanium ore

Titanium ore is an important metal mineral resource, among which coastal titanium ore is currently one of the most important in the world. The beneficiation method of coastal titanium ore is of great significance for improving the grade and recovery rate of titanium ore. This article will introduce the beneficiation methods of coastal titanium ore.

1. Beneficiation process of Binhai titanium ore

The beneficiation process of Binhai titanium ore mainly includes four steps: grinding, roughing, selection, and tailings treatment.

1. Grinding

Grinding is the process of breaking the original ore into a certain particle size. The grinding of coastal titanium ore is usually carried out using a ball mill, and the particle size of the ore after grinding is generally around -200 mesh.

2. Rough selection

Rough sorting is the preliminary physical sorting of the ground ore, separating the waste rock and useful minerals from it. The coarse separation of coastal titanium ore is usually carried out using a heavy medium separator, which places the ore in the heavy medium to separate it into layers and then separates the heavy and light minerals.

3. Selection

Selection refers to the further physical or chemical separation of the roughened ore to improve the grade and recovery rate of useful minerals in the ore. The selection of coastal titanium ore is usually carried out by flotation method, where the ore is immersed in a reagent to undergo a chemical reaction with the reagent, and then useful minerals are floated out.

4. Tailings treatment

Tailings treatment is the treatment of the waste residue in the selected ore to reduce its impact on the environment. The tailings treatment of coastal titanium ore is usually carried out by leaching method, where the waste residue is immersed in a reagent to undergo a chemical reaction with the reagent, and then the harmful substances are removed.

2、 Beneficiation technology of coastal titanium ore

The beneficiation technology of Binhai titanium ore mainly includes methods such as heavy medium separation, flotation, magnetic separation, and electrical separation.

1. Heavy medium sorting

Heavy medium separation is a method of separating ores by utilizing the difference in their specific gravity in the heavy medium. The proportion of titanium Magnetite and Galena in coastal titanium ore is large, while the proportion of other minerals is small. Therefore, titanium Magnetite and Galena can be separated by heavy medium separation.

2. Flotation

Flotation is a method of separation that utilizes the differences in the hydrophilicity between ores and reagents in water. Titanium Magnetite and Galena in coastal titanium ore are less hydrophilic, while other minerals are more hydrophilic, so titanium Magnetite and Galena can be floated out by flotation.

3. Magnetic separation

Magnetic separation is a method of separating minerals by utilizing their magnetic differences in the magnetic field. Titanium Magnetite and Galena in coastal titanium ore have certain magnetism, while other minerals have no magnetism, so titanium Magnetite and Galena can be separated from them by magnetic separation.

4. Electrical selection

Electric separation is a method of separating minerals by utilizing their electrical differences in an electric field. Titanium Magnetite and Galena in coastal titanium ore have a certain electrical property, while other minerals have no electrical property. Therefore, titanium Magnetite and Galena can be separated from them by electric separation.

3、 Optimization of beneficiation methods for coastal titanium ore

In order to improve the beneficiation efficiency and grade of coastal titanium ore, the following measures can be taken:

1. Optimize the reagent ratio to improve the recovery rate and grade of flotation.

2. Optimize the process flow of magnetic and electrical separation to improve sorting efficiency.

3. Optimize the tailings treatment process to reduce its impact on the environment.

4. Introduce new beneficiation technologies, such as high-pressure roller mills and air flotation separators, to improve beneficiation efficiency and grade.

4、 Conclusion

The beneficiation method of coastal titanium ore is a complex process that requires the comprehensive use of various physical, chemical, and mechanical methods. By optimizing the beneficiation process and introducing new beneficiation technologies, the grade and recovery rate of coastal titanium ore can be improved, achieving efficient utilization of resources.
