Gravity beneficiation method of Ilmenite

Gravity beneficiation method of Ilmenite

Ilmenite is an important mineral resource, which is widely used in metallurgy, chemical industry, aerospace and other fields. However, there are many problems in the mining and beneficiation process of Ilmenite, such as low ore grade and difficult to achieve beneficiation indicators. In order to solve these problems, many Ilmenite beneficiation methods have been developed, among which gravity beneficiation method is a commonly used method.

1、 The principle of gravity beneficiation method

Gravity beneficiation method is a method of separating materials by utilizing their different characteristics in the gravity field. In Ilmenite beneficiation, common gravity beneficiation equipment includes flotation machine, heavy medium concentrator, spiral separator, etc.

II. Operating steps of gravity beneficiation method for Ilmenite

1. Ore crushing: crush Ilmenite to make its particle size meet the mineral processing requirements.

2. Ore screening: Screen the crushed ore to remove oversized or undersized ores.

3. Heavy medium beneficiation: put the ore into the heavy medium concentrator, and use the density difference of the medium for separation. Generally, the flotation index of Ilmenite is relatively high, and the heavy medium concentrator can increase its flotation index to more than 90%.

4. Spiral sorting: Place the ore after beneficiation into a spiral sorting machine and use the movement characteristics of the ore on the spiral for separation. The spiral sorting machine can increase the grade of ore to over 95%.

3、 Advantages of gravity beneficiation method for Ilmenite

1. Good beneficiation effect: gravity beneficiation method can increase the grade of Ilmenite to more than 90%.

2. Simple operation: The gravity beneficiation method is simple in operation and does not require complex equipment and technology.

3. Low cost: The gravity beneficiation method has a low cost and is suitable for beneficiation in small and medium-sized mines.

IV. Limitations of gravity beneficiation method for Ilmenite

1. Poor adaptability to ores: Gravity beneficiation methods have poor adaptability to ores and can only handle ores within a certain range.

2. High requirements for ore: Gravity beneficiation methods have high requirements for ore and require pre-treatment of the ore.

3. The beneficiation index is difficult to reach: the beneficiation index of gravity beneficiation method is difficult to meet some special requirements, such as the flotation index of Ilmenite is high.

5、 Conclusion

Gravity beneficiation of Ilmenite is a common beneficiation method, which has the advantages of good beneficiation effect, simple operation and low cost. However, we also need to pay attention to the limitations of this method, and we need to select appropriate beneficiation methods according to different ore characteristics.
