Beneficiation methods for tungsten ore

Tungsten ore is an important metal ore with a high tungsten content, which is widely used in the manufacturing of high-speed steel, hard alloys, electronic devices, and other fields. However, the beneficiation process of tungsten ore is not simple and requires a series of beneficiation methods to improve the grade and recovery rate of tungsten ore. This article will introduce the beneficiation methods of tungsten ore, including gravity separation, flotation, magnetic separation, and chemical beneficiation.

1、 Reselection

Gravity separation refers to the method of separating tungsten ores by using the density difference of tungsten minerals in tungsten ores. Due to the high density of tungsten minerals, they can be separated from other minerals through gravity separation. The specific operation steps are as follows:

1. Tungsten ore is processed through crushing, grinding, and other processes before being sent to a gravity separator for sorting.

The working principle of a gravity separator is to use the buoyancy of water to divide minerals into two parts: heavy ore and light ore. Heavy minerals are tungsten containing minerals, while light minerals are other minerals.

3. After separation, the heavy ore undergoes secondary separation to improve grade and recovery rate.

2、 Flotation

Flotation refers to the method of separating tungsten minerals from other minerals by utilizing their surface properties. Due to the different surface properties of tungsten minerals from other minerals, they can be separated from other minerals through flotation. The specific operation steps are as follows:

1. Tungsten ore is processed through processes such as crushing and grinding, and then sent to a flotation machine for sorting.

2. The working principle of flotation machine is to use bubbles to divide minerals into flotation foam and sediment. The flotation foam contains tungsten minerals, and the precipitates are other minerals.

3. The flotation foam after separation shall be subject to secondary separation to improve the grade and recovery rate.

III. Magnetic Separation

Magnetic separation refers to the method of separating tungsten minerals from other minerals by utilizing their magnetic differences. Due to its different magnetic properties from other minerals, tungsten minerals can be separated from other minerals through magnetic separation. The specific operation steps are as follows:

1. Tungsten ore is processed through processes such as crushing and grinding, and then sent to a magnetic separator for sorting.

The working principle of a magnetic separator is to use a magnetic field to divide minerals into two parts: magnetic and non magnetic. Magnetic minerals are tungsten containing minerals, while non magnetic minerals are other minerals.

3. The sorted magnetic ore undergoes secondary sorting to improve grade and recovery rate.

4、 Chemical beneficiation

Chemical beneficiation refers to the method of separating tungsten minerals from other minerals through chemical reactions. Due to the different reactivity between tungsten minerals and other minerals in chemical reactions, they can be separated from other minerals through chemical beneficiation. The specific operation steps are as follows:

1. Tungsten ore is processed through processes such as crushing and grinding, and then sent to a chemical beneficiation tank for sorting.

2. Add specific chemical reagents to the chemical beneficiation tank to react with the ore. Tungsten minerals have different reactivity with other minerals during the reaction process, so tungsten containing minerals can be separated.

3. The sorted tungsten containing minerals are further sorted to improve grade and recovery rate.

summary

The beneficiation methods of tungsten ore include gravity separation, flotation, magnetic separation, and chemical beneficiation. These beneficiation methods have their own advantages and disadvantages, and suitable methods should be selected based on the specific situation for beneficiation. At the same time, attention should be paid to the grade and recovery rate of the ore during the beneficiation process to improve the economic benefits of tungsten ore.
