New Technology for Recovery of Tungsten Tin Tailings

New Technology for Recovery of Tungsten Tin Tailings

Tungsten tin tailings refer to the waste produced in the process of extracting tungsten tin from tungsten Xikuangshan Mine. Because the waste produced in the mining and extraction process of tungsten and tin mines contains a large number of harmful substances and heavy metals, the treatment of tungsten and tin tailings has always been a difficult problem. Traditional processing methods often require a large amount of manpower, material resources, and financial resources, and the processing effect is not satisfactory. In recent years, with the continuous progress of technology, new technologies for the recovery of tungsten tin tailings have emerged, providing new ideas and methods for the treatment of tungsten tin tailings.

1. Hazards of tungsten tin tailings

Tungsten tin tailings contain a large amount of harmful substances and heavy metals, such as lead, zinc, copper, cadmium, chromium, etc. These substances have great harm to the environment and human health. If discharged arbitrarily, it will seriously pollute soil, water sources, and air, causing serious impacts on the surrounding ecological environment. Moreover, these harmful substances may also enter the human body through the food chain, causing damage to human health and even leading to the occurrence of diseases such as cancer.

2、 Traditional methods for treating tungsten tin tailings

There are two main traditional methods for treating tungsten tin tailings: landfill and flotation. Landfill is the direct burial of tungsten tin tailings underground. Although this method is simple, it can seriously pollute the soil and groundwater, and have a serious impact on the environment. Flotation is the process of separating useful minerals from tungsten tin tailings through physical and chemical methods. Although this method can recover some useful minerals, the treatment effect is not satisfactory and requires a lot of manpower, material resources, and financial resources.

III. New Technology for Recovery of Tungsten Tin Tailings

The new technologies for recovering tungsten tin tailings mainly include microbial methods, chemical methods, and pyrolysis methods. These new technologies can not only recover useful minerals but also effectively remove harmful substances and heavy metals in the treatment of tungsten tin tailings, reducing the harm to the environment and human health.

1. Microbiological method

Microbial method refers to the method of utilizing microorganisms to decompose and transform useful minerals and harmful substances in tungsten tin tailings. This method not only recycles useful minerals, but also effectively removes harmful substances and heavy metals, with dual benefits of environmental protection and economy. At present, the microbial method has been applied in some tungsten Xikuangshan Mine and achieved good results.

2. Chemical method

Chemical method refers to the method of separating and transforming useful minerals and harmful substances in tungsten tin tailings through chemical reactions. This method requires the use of chemical reagents and requires certain technical and equipment support. However, chemical methods can effectively separate useful minerals and harmful substances from tungsten tin tailings, which has a good treatment effect.

3. Pyrolysis method

Pyrolysis refers to the method of decomposing and converting tungsten tin tailings at high temperatures. This method requires the use of high-temperature equipment and technical support, but it can effectively separate useful minerals and harmful substances from tungsten tin tailings and has good treatment effects.

4、 Conclusion

The treatment of tungsten tin tailings has always been a challenge, and traditional treatment methods often have unsatisfactory results. With the continuous progress of technology, new technologies for the recovery of tungsten tin tailings have emerged, providing new ideas and methods for the treatment of tungsten tin tailings. New technologies such as microbial method, chemical method, and pyrolysis method can not only recover useful minerals but also effectively remove harmful substances and heavy metals in the treatment of tungsten tin tailings, reducing the harm to the environment and human health.
