How to sort tungsten ore

Tungsten ore is an important metal ore, whose main component is Tungstate. The separation of tungsten ore refers to the separation of Tungstate from tungsten ore for subsequent smelting and processing. There are many methods for separating tungsten ore, and now we will have a detailed understanding.

1、 Gravity separation of tungsten ore

Gravity separation is a common method of tungsten ore separation. It uses the difference of physical properties to separate Tungstate from tungsten ore. Firstly, the tungsten ore is crushed into particles of a certain size, and then placed in a gravity separator for sorting. Due to the large proportion of Tungstate, the water flow speed and swing amplitude of the machine can be adjusted in the gravity separator to make Tungstate deposit to the bottom, while other impurities are washed out.

2、 Flotation separation of tungsten ore

Flotation method is a method of sorting that utilizes differences in chemical properties. First, the tungsten ore is broken into particles of a certain size, and then reagents are added so that Tungstate can be adsorbed on the bubbles to float. However, other impurities cannot adsorb on the bubbles and still deposit at the bottom. Finally, Tungstate can be separated by separating bubbles and liquid.

III. Magnetic Separation for Tungsten Ore Separation

Magnetic separation is a method of sorting that utilizes magnetic differences. Tungstate has certain magnetism, while other impurities have no magnetism. Therefore, tungsten ore can be placed in a magnetic separator for sorting. Under the action of magnetic field, Tungstate will be adsorbed on the magnetic pole, while other impurities will not. Finally, Tungstate can be separated by adjusting parameters such as magnetic field strength and machine speed.

4、 Gravity separation of tungsten ore

Gravity sorting method is a method of sorting that utilizes gravity differences. The specific gravity of Tungstate is large, while that of other impurities is small. Therefore, tungsten ore can be placed in a gravity separator for sorting. Under the action of gravity, Tungstate will deposit to the bottom, while other impurities will float. Finally, Tungstate can be separated by adjusting the tilt angle of the machine and the water flow speed and other parameters.

5、 Separation of tungsten ore by electric separation method

The electrical separation method is a method of sorting using electrical differences. Tungstate has certain conductivity, while other impurities have no conductivity. Therefore, tungsten ore can be placed in an electric separator for sorting. Under the action of electric field, Tungstate will be adsorbed on the electrode, while other impurities will not. Finally, Tungstate can be separated by adjusting parameters such as electric field strength and machine speed.

summary

Tungsten ore sorting is a very important task, and its sorting methods are diverse. According to different tungsten ore properties and production needs, different sorting methods can be selected. Gravity separation, flotation, magnetic separation, gravity separation, and electric separation are commonly used separation methods, each of which has its unique advantages and applicability. In actual production, the most suitable separation method should be selected based on the specific situation to improve the recovery rate and quality of tungsten ore.
