Tin tungsten ore gravity separation technology

Tin tungsten ore gravity separation technology

Tin tungsten ore is an important mineral resource with extensive application value. However, the mining and utilization of tin tungsten ore also face a series of problems, such as low ore grade, fine particle size, and difficulty in selection. Therefore, the research and application of tin tungsten ore gravity separation technology is particularly important. This article will introduce the relevant knowledge and operational steps of tin tungsten ore gravity separation technology, hoping to provide some reference for the mining and utilization of tin tungsten ore.

1、 Characteristics of tin tungsten ore

Tin tungsten ore is a hard mineral containing tin and tungsten, usually appearing black or brown. Tin tungsten ore is mainly composed of quartz, Galena, wolframite, Scheelite, etc. The grade of tin tungsten ore is relatively low, usually between 0.1% and 0.3%, and the ore particle size is relatively fine, usually below 0.02mm. Tin tungsten ore is difficult to separate, mainly due to the density difference between minerals, surface electrical differences and other factors.

2、 Classification of gravity separation technology for tin tungsten ore

The gravity separation technology of tin tungsten ore mainly includes methods such as heavy medium beneficiation, flotation, magnetic separation, etc. Among them, heavy medium beneficiation and flotation are commonly used methods.

1. Heavy medium beneficiation

Heavy medium beneficiation is a method of separating ores using media of different densities. This method has certain requirements for ore particle size, generally requiring ore particle size to be above 0.5mm. The operating steps for heavy medium beneficiation are as follows:

(1) Ore crushing: After preliminary crushing of tin tungsten ore, the particle size meets the requirements.

(2) Heavy medium preparation: Select a suitable medium to prepare heavy medium based on the density of the ore.

(3) Heavy medium beneficiation: put ore into heavy medium, and make minerals with different densities settle to different locations according to density differences. Then, sorting equipment is used to sort minerals of different densities.

2. Flotation

Flotation is the use of differences in surface properties of minerals to attach them to bubbles, thereby achieving the separation of minerals. The operation steps of flotation are as follows:

(1) Ore crushing: After preliminary crushing of tin tungsten ore, the particle size meets the requirements.

(2) Reagent addition: Different reagents are added based on the surface properties of minerals to make them adhere to bubbles.

(3) Flotation separation: Add reagents to the slurry, then float the minerals through bubbles, and finally use sorting equipment to separate the minerals.

3、 Application of Tin Tungsten Ore Gravity Separation Technology

The heavy separation technology of tin tungsten ore has been widely applied, mainly in the mining and utilization of tin tungsten ore. Tin tungsten ore gravity separation technology can improve the grade of the ore, reduce production costs, and improve production efficiency. At the same time, tin tungsten ore gravity separation technology can also reduce the impact on the environment and protect the ecological environment.

4、 Summary

Tin tungsten ore is an important mineral resource, and the research and application of tin tungsten ore gravity separation technology is of great significance for the mining and utilization of tin tungsten ore. This article introduces the relevant knowledge and operational steps of tin tungsten ore gravity separation technology, hoping to provide some reference for the mining and utilization of tin tungsten ore.
