Method for gravity separation of tungsten tin tailings

Tungsten tin tailings refer to the remaining waste after extracting tungsten and tin from tungsten and tin ores. This waste contains a certain amount of tungsten and tin. If it can be effectively re selected, the tungsten and tin can be extracted again, thereby achieving resource reuse. This article will introduce a method of tungsten tin tailings gravity separation to help readers better understand and master this technology.

1、 The principle of tungsten tin tailings gravity separation

The principle of tungsten tin tailings gravity separation is to separate tungsten and tin from the tailings by utilizing differences in physical and chemical properties. Specifically, tungsten and tin have a relatively high density and can be separated by gravity separation. At the same time, tungsten and tin have different magnetic properties and can be separated by magnetic separation. In addition, tungsten and tin can also be separated through methods such as flotation and chemical separation.

2、 Steps of tungsten tin tailings re selection

The steps of gravity separation for tungsten tin tailings at the rate of 钨锡尾矿重选方法 mainly include grinding, gravity separation, flotation, chemical separation, and other processes. The following will provide a detailed introduction to the operational steps of each link.

钨锡尾矿重选方法1. Grinding

Grinding is the process of crushing and grinding the original tungsten tin tailings ore. The purpose of this process is to break the ore into smaller particles for subsequent processes such as gravity separation and flotation. Grinding equipment usually includes ball mills, grinders, etc.

2. Reselection

Gravity separation is the process of separating the finely ground tailings. The method of gravity separation and magnetic separation is usually used for re selection. In gravity separation, methods such as heavy medium separation and centrifugal separation can be used. In magnetic separation, methods such as weak magnetic separation and strong magnetic separation can be used.

3. Flotation

Flotation is the process of separating tungsten tin tailings after gravity separation. The principle of flotation is to separate minerals from water by utilizing their different hydrophilicity and hydrophobicity with water. In flotation, methods such as air flotation and oil flotation can be used.

4. Chemical selection

Chemical separation is the process of further processing the flotation tailings. The methods of chemical selection usually include oxidation, reduction, dissolution, etc. In chemical selection, methods such as oxidation roasting, reduction roasting, and acid leaching can be used.

3、 Advantages of tungsten tin tailings gravity separation

The advantages of tungsten tin tailings gravity separation are mainly reflected in the following aspects:

1. High resource utilization rate: Gravity separation can extract tungsten and tin from tailings again, thereby achieving resource reuse.

2. Environmental protection and energy conservation: During the re selection process, no chemical reagents need to be added, and no pollutants will be generated, meeting environmental requirements.

3. Good economic benefits: Gravity separation can extract tungsten and tin from tailings, thereby achieving resource reuse and achieving good economic benefits.

4、 Conclusion

Tungsten tin tailings gravity separation is a very important technology that can effectively achieve resource reuse while also meeting environmental requirements. This article introduces the principle, steps, and advantages of tungsten tin tailings gravity separation, hoping to help readers better understand and master this technology.
