Gravity beneficiation technology for tungsten tin tailings

Tungsten tin tailings are a type of waste containing various metals such as tungsten and tin, usually generated by mines or smelters. These wastes contain a large amount of useful metals, but due to their high impurity content, they are difficult to extract directly. In order to effectively recover these useful metals, researchers have developed a gravity beneficiation technology for tungsten tin tailings.

1、 The principle of gravity beneficiation technology for tungsten tin tailings

gravity beneficiation technology for tungsten tin tailings is a beneficiation technology based on the gravity Separation principle, which uses the different characteristics of materials in the gravity field to separate materials containing useful metals from impurities. In this technology, the material is first subjected to rough selection, separating large blocks of ore from impurities. Then, the material enters the fine selection stage, utilizing the different characteristics of materials with different weights in the gravity field to separate materials containing useful metals from impurities.

2 II. Operating Steps of Gravity Beneficiation Technology for Tungsten Tin Tailings

1. Roughing stage: Feed the raw material containing tungsten tin tailings into the roughing machine, and separate the large ore from impurities through screening.

2. Fine selection stage: The roughly selected materials are fed into the fine selection machine, and the different characteristics of the materials in the gravity field are utilized to separate the materials containing useful metals from impurities. Generally speaking, a centrifuge or gravity separator is used for fine sorting.

3. Magnetic separation stage: The finely selected material is fed into the magnetic separator and separated from impurities by magnetic force.

4. Flotation stage: The material after magnetic separation is fed into the flotation machine, and the material containing useful metals is separated from impurities through bubbles.

5. Dehydration stage: The flotation material is fed into the dehydrator to remove moisture from the material.

3、 Advantages of gravity beneficiation technology for tungsten tin tailings

1. Efficient: The gravity beneficiation technology of tungsten tin tailings can efficiently separate materials containing useful metals from impurities, improving metal recovery rate.

2. Environmental protection: The gravity beneficiation technology of tungsten tin tailings does not require the use of chemical reagents and has minimal impact on the environment.

3. Economy: The gravity beneficiation technology for tungsten tin tailings is simple to operate, does not require a large amount of equipment and manpower investment, and has lower costs.

4、 Conclusion

The gravity beneficiation technology of tungsten tin tailings is an efficient, environmentally friendly, and economical beneficiation technology. Through multiple stages of operations such as rough selection, fine selection, magnetic separation, flotation, and dehydration, materials containing useful metals can be separated from impurities, improving metal recovery rate. In future mineral development, the gravity beneficiation technology of tungsten tin tailings will be more widely applied.
