Tungsten sand gravity separation method

Tungsten is an important metal element with high melting point, high density, and high strength, widely used in aviation, aerospace, electronics, chemical and other fields. Tungsten sand is a common form of tungsten, characterized by high density, high hardness, and high melting point. It is an important raw material for preparing tungsten alloys, tungsten wires, electrodes, and other materials. In the production process of tungsten sand, due to the presence of impurities in the ore, tungsten sand often contains impurities, which affect its quality and purity. Therefore, it is necessary to re select tungsten sand to remove impurities and improve its purity. This article will introduce the methods and steps of tungsten sand re selection.

1、 Material preparation

Before conducting tungsten sand re selection, the following materials and equipment need to be prepared:

1. Tungsten sand: Choose high-quality and less impurity tungsten sand as the raw material.

2. Water: Used for flushing and separating tungsten sand.

3. Magnetic separator: used for magnetic separation to remove magnetic substances from it.

4. Gravity separator: used for gravity separation to remove heavy substances from it.

II. Magnetic Separation

Place tungsten sand into a magnetic separator for magnetic separation to remove any magnetic substances. The working principle of a magnetic separator is to utilize the action of magnetic substances in the magnetic field to adsorb the magnetic substances on the magnetic poles, thereby achieving separation. The selection of magnetic separators should be based on the properties and requirements of tungsten sand.

3、 Reselection

Place the magnetically separated tungsten sand into a gravity separator for gravity separation to remove heavy substances. The working principle of the gravity separator is to use the effect of materials in the water flow to separate according to their density differences. The selection of the gravity separator should be based on the properties and requirements of the tungsten sand.

4、 Flushing

Wash the re selected tungsten sand in water to remove light substances and impurities. During the flushing process, attention should be paid to the size and direction of the water flow to avoid dispersing the re selected tungsten sand.

5、 Drying

Dry the washed tungsten sand in a dryer to achieve the desired dryness. The drying temperature and time should be based on the properties and requirements of tungsten sand.

6、 Quality inspection

Conduct quality inspection on the re selected tungsten sand to check its purity and quality for compliance with requirements. The methods and standards for quality inspection should be based on the purpose and requirements of tungsten sand.

7、 Packaging

Pack, store, and transport tungsten sand that has passed quality inspection. The packaging method and materials should be selected based on the properties and requirements of tungsten sand.

Summary:

Tungsten sand gravity separation is an important method to improve the purity and quality of tungsten sand, which includes material preparation, magnetic separation, gravity separation, flushing, drying, quality inspection, and packaging. When conducting tungsten sand re selection, appropriate equipment and methods should be selected based on the properties and requirements of tungsten sand, and the parameters and quality of each step should be strictly controlled to ensure that the quality and purity of tungsten sand meet the requirements.
