Technological process for selecting tin tungsten ore

Tin and tungsten are two important metals that have extensive applications in industrial production. The main ores of tin and tungsten are cassiterite and Wolframite, and the beneficiation process is the Committed step to extract tin and tungsten from the ores. In this article, we will delve into the process of selecting tin tungsten ore.

1、 Properties of ore

Cassiterite and Wolframite are two different ores with different properties. Cassiterite is mainly composed of Tin(IV) oxide, with hardness of 4~4.5 and specific gravity of 6.8~7.1g/cm ³。 Wolframite is mainly composed of tungsten trioxide, with hardness of 5~5.5 and specific gravity of 7.0~7.5g/cm ³。 In the process of selecting tin tungsten ore, it is necessary to choose a suitable beneficiation process based on the properties of the ore.

II. Process of selecting tin tungsten ore

1. Rough selection

Coarse beneficiation is the first step in mineral processing, with the aim of separating waste rock from useful minerals in the ore. The gravity separation method is usually used to put the ore into the gravity separator, and use the density difference of the ore to separate the waste rock and useful minerals. In the process of selecting cassiterite, manual selection is often used to classify the ore according to its color, shape, and other characteristics.

2. Successful selection

Intermediate separation is the process of further separating the ore obtained from rough separation. According to the properties of the ore, different beneficiation processes such as flotation, magnetic separation, and gravity separation can be used. In the process of selecting cassiterite, flotation method is usually used, where the ore is placed in a flotation machine to separate cassiterite from waste rock by utilizing the difference in the affinity between the ore and water.

3. Selection

Selection is the process of further purifying the ore obtained from the selection. According to the properties of the ore, different beneficiation processes such as gravity separation, magnetic separation, and flotation can be used. In the process of selecting cassiterite, the combination of gravity separation and flotation is usually used to put the ore into the gravity separator, separate cassiterite and waste rock by using the density difference of ore, and then put the cassiterite into the flotation machine, and separate cassiterite and waste rock by using the difference in the affinity between ore and water.

3、 Precautions for selecting tin tungsten ore

1. Storage of ore

During the storage process of ore, it is necessary to avoid moisture, heat, pollution, and other conditions to avoid affecting the beneficiation effect.

2. Equipment maintenance

Mineral processing equipment requires regular maintenance and upkeep to ensure its normal operation and the effectiveness of mineral processing.

3. Optimization of process

The beneficiation process needs to be optimized based on the properties and effectiveness of the ore, in order to improve the efficiency and quality of beneficiation.

4、 Conclusion

The process of selecting tin tungsten ore is a complex process that requires selecting appropriate beneficiation processes based on the properties of the ore and the requirements of beneficiation. During the beneficiation process, attention needs to be paid to issues such as ore storage, equipment maintenance, and process optimization to improve the efficiency and quality of beneficiation.
