Tin tungsten ore beneficiation technology

Tin tungsten ore beneficiation technology

Tin tungsten ore is an important metal ore, which contains metal elements such as tin and tungsten, which are widely used in industrial production. In order to improve the utilization rate of tin tungsten ore and reduce environmental pollution, mining enterprises have adopted various beneficiation technologies. This article will introduce several common tin tungsten ore beneficiation technologies and analyze their advantages and disadvantages.

1、 Reselection method

Gravity separation method is a common technology for dressing tin tungsten ores, which mainly utilizes the different specific gravity differences of minerals in the heavy liquid for separation. The specific steps are as follows:

1. Crush the ore sample into particles within a certain particle size range.

2. Place the granular ore sample into the heavy liquid, and according to the difference in specific gravity of different minerals, the minerals will be layered in the heavy liquid.

3. Collect and sort the layered minerals to obtain mineral concentrates containing metallic elements such as tin and tungsten.

The advantage of the gravity separation method is that it has good beneficiation efficiency and can achieve high beneficiation indicators. But its drawbacks are also obvious, requiring a large amount of heavy liquid, causing environmental pollution, and also wasting a large amount of energy.

2、 Flotation method

The flotation method is a common technology for dressing tin tungsten ores, which mainly utilizes the differences in hydrophilicity and hydrophobicity of minerals under the action of bubbles for separation. The specific steps are as follows:

1. Crush the ore sample into particles within a certain particle size range.

2. Place the granular ore sample into a flotation cell and add a certain amount of reagent to produce hydrophilicity or hydrophobicity on the mineral surface.

3. Through the action of bubbles, hydrophilic minerals sink to the bottom, while hydrophobic minerals float on the water surface.

4. Collect and sort the minerals after flotation to obtain mineral concentrates containing metallic elements such as tin and tungsten.

The advantage of the flotation method is that it has good beneficiation efficiency and can also reduce environmental pollution. But its drawbacks are also obvious, requiring a large amount of chemicals, resulting in resource waste and environmental pollution.

3、 Magnetic separation method

The magnetic separation method is a common tin tungsten ore beneficiation technology, which mainly utilizes the magnetic differences of minerals under the action of a magnetic field for separation. The specific steps are as follows:

1. Crush the ore sample into particles within a certain particle size range.

2. Place the granular ore sample in a magnetic field, and according to the magnetic differences of different minerals, the minerals will separate in the magnetic field.

3. Collect and sort the separated minerals to obtain mineral concentrates containing metallic elements such as tin and tungsten.

The advantage of magnetic separation method is that it has good beneficiation effect and can also reduce environmental pollution. However, its drawbacks are also obvious, requiring a large amount of magnetic field equipment, resulting in resource waste and environmental pollution.

In summary, there are various beneficiation technologies for tin tungsten ore, each with its own advantages and disadvantages. In practical applications, it is necessary to select appropriate technologies based on specific circumstances to achieve the best beneficiation effect and environmental benefits.
