What methods can be used to separate tungsten ore

Tungsten ore is an important metal ore that contains high concentrations of tungsten element and is the main raw material for manufacturing high-speed steel and hard alloys. The separation of tungsten ore is an important technological process, which aims to separate tungsten elements from other impurities in tungsten ore, in order to improve the purity and value of tungsten ore. This article will introduce several common methods for tungsten ore separation.

1、 Reselection method

Gravity separation is a common method for tungsten ore separation, which is based on the density difference of the ore. In this method, the ore is first broken into particles of a certain size, and then placed in a gravity separator for sorting. Gravity separators usually use equipment such as flotation machines, centrifuges, and gravity separators. By adjusting the working parameters of the separator, such as rotation speed, water flow rate, slope, etc., tungsten ore can be separated.

2、 Flotation method

Flotation method is a method of separation that utilizes differences in mineral surface properties. In this method, the ore is first broken into particles of a certain size, and then placed in a flotation cell. A certain amount of reagent is added to create hydrophilicity or hydrophobicity on the surface of the tungsten ore, thereby achieving separation from other impurities. The flotation method usually uses equipment such as air flotation separators and mechanical flotation machines.

3、 Magnetic separation method

Magnetic separation is a method of separating minerals by utilizing their magnetic differences. In this method, the ore is first broken into particles of a certain size, and then placed in a magnetic separator for sorting. Magnetic separators usually use high-strength magnetic fields, and by adjusting the strength and direction of the magnetic field, tungsten ore can be separated.

4、 Electroselection method

The electrical separation method is a method of sorting by utilizing differences in mineral conductivity. In this method, the ore is first broken into particles of a certain size, and then placed in an electric separator for sorting. The electric separator usually uses a high-voltage electric field, and by adjusting the intensity and direction of the electric field, tungsten ore can be sorted.

summary

The above are several common tungsten ore sorting methods, each with its own advantages and disadvantages. You can choose the appropriate method for sorting according to the specific situation. In practical applications, appropriate process design and parameter adjustments need to be made based on the properties and sorting requirements of the ore to achieve the best sorting effect.
