Beneficiation technology of tungsten tin tailings

Tungsten tin tailings refer to the remaining stones, slag and other wastes after the mining of tungsten Xikuangshan Mine. These wastes contain a large amount of valuable metals such as tungsten and tin. If effective mineral processing can be carried out, these valuable metals can be extracted, bringing rich economic benefits to enterprises. This article will introduce the beneficiation technology of tungsten tin tailings, helping readers understand the beneficiation treatment methods of tungsten tin tailings.

1、 Overview of beneficiation technology for tungsten tin tailings

Tungsten tin tailings beneficiation technology refers to the physical, chemical and other methods of beneficiation treatment of tungsten tin tailings to extract valuable metals from them. The commonly used tungsten tin tailings beneficiation techniques currently include gravity separation, flotation, chemical beneficiation, etc.

The gravity separation method utilizes the differences in physical properties of tungsten tin tailings and conducts mineral processing through methods such as gravity separation and magnetic separation. The flotation method utilizes the differences in chemical properties of tungsten tin tailings and conducts mineral processing through methods such as bubble adsorption and surfactants. The chemical beneficiation method utilizes the differences in chemical properties of tungsten tin tailings and conducts beneficiation treatment through chemical reactions, ion exchange, and other methods.

2、 Gravity beneficiation technology

The gravity separation method is the most commonly used method in tungsten tin tailings beneficiation technology. This method is suitable for the separation of hard minerals such as quartz and feldspar from soft minerals such as tungsten and tin tailings. The specific operation steps are as follows:

1. Crushing: coarse crushing and fine crushing of tungsten tin tailings to make its Granularity meet the mineral processing requirements.

2. Gravity separation: Gravity separation is carried out on tungsten tin tailings, using gravity differences to separate soft minerals such as tungsten ore and tin ore from hard minerals such as quartz and feldspar.

3. Magnetic separation: Magnetic separation is carried out on soft minerals such as tungsten ore and tin ore after gravity separation, and magnetic differences are used to separate them from hard minerals such as non-magnetic quartz and feldspar.

4. Selection: Select soft minerals such as tungsten and tin ore after magnetic separation to remove impurities and improve grade.

3、 Flotation beneficiation technology

Flotation method is another commonly used method in tungsten tin tailings beneficiation technology. This method is applicable to the separation of hard minerals such as tungsten ore and tin ore from soft minerals such as quartz and feldspar in tungsten tin tailings. The specific operation steps are as follows:

1. Crushing: coarse crushing and fine crushing of tungsten tin tailings to make its Granularity meet the requirements of mineral processing.

2. Flotation: The tungsten tin tailings are subjected to flotation treatment, and hard minerals such as tungsten ore and tin ore are separated from soft minerals such as quartz and feldspar using methods such as bubble adsorption and surfactants.

3. Magnetic separation: Magnetic separation is carried out on hard minerals such as tungsten ore and tin ore after flotation, and magnetic differences are used to separate them from soft minerals such as non-magnetic quartz and feldspar.

4. Selection: Select hard minerals such as tungsten and tin ore after magnetic separation to remove impurities and improve grade.

IV. Chemical beneficiation technology

Chemical beneficiation method is a relatively complex method in tungsten tin tailings beneficiation technology. This method is applicable to the separation of hard minerals such as tungsten ore and tin ore from soft minerals such as quartz and feldspar in tungsten tin tailings. The specific operation steps are as follows:

1. Crushing: coarse crushing and fine crushing of tungsten tin tailings to make its Granularity meet the requirements of mineral processing.

2. Chemical reaction: Conduct a chemical reaction on tungsten tin tailings, using the principle of chemical reaction to separate hard minerals such as tungsten ore and tin ore from soft minerals such as quartz and feldspar.

3. Ion exchange: Ion exchange is carried out on hard minerals such as tungsten ore and tin ore after chemical reactions to remove impurities and improve grade.

4. Selection: Select hard minerals such as tungsten and tin after ion exchange to remove impurities and improve grade.
