How to remove silicon from tungsten ore beneficiation

Tungsten ore is an important metal ore that contains a large amount of tungsten and silicon. In the beneficiation process of tungsten ore, removing silicon is a very important step. Because the presence of silicon can affect the extraction efficiency and quality of tungsten. So, how does tungsten ore beneficiation remove silicon? Next, let's take a closer look.

1、 Flotation method

Flotation method is a commonly used method for tungsten ore beneficiation, which can effectively remove silicon. The specific operation steps are as follows:

1. Crush tungsten ore to a certain particle size, usually below 0.074mm.

2. Put the crushed tungsten ore into a flotation cell and add an appropriate amount of reagents, such as paraffin oil, xanthate water, etc.

3. Start the flotation machine to fully mix the tungsten ore with the reagent.

4. By adjusting the water level and air volume of the flotation machine, the silicon ore is floated and collected by the collector to achieve the purpose of removing silicon.

2、 Reselection method

The gravity separation method is also a commonly used method for tungsten ore beneficiation, which can remove silicon through the action of gravity. The specific operation steps are as follows:

1. Crush tungsten ore to a certain particle size, usually below 0.074mm.

2. Put the crushed tungsten ore into the gravity separator and add an appropriate amount of water and reagents.

3. Start the gravity separator to separate minerals of different densities from tungsten ore under the action of gravity.

4. By adjusting the parameters of the gravity separator, the silicon ore is separated, thereby achieving the goal of removing silicon.

III. Chemical method

Chemical method is a relatively special method for tungsten ore beneficiation, which can remove silicon through chemical reactions. The specific operation steps are as follows:

1. Crush tungsten ore to a certain particle size, usually below 0.074mm.

2. Put the crushed tungsten ore into a reaction kettle and add an appropriate amount of acid or alkali.

3. Heat the reaction kettle to cause a chemical reaction between acid or alkali and silicon ore, thereby removing the silicon ore.

4. Remove the tungsten ore from the reaction kettle for subsequent beneficiation treatment.

Summary of

Removing silicon from tungsten ore beneficiation is a very important step, which directly affects the extraction efficiency and quality of tungsten. Flotation, gravity separation, and chemical methods can all be used to remove silicon, and the specific method chosen depends on the characteristics of tungsten ore and beneficiation process. Regardless of the method used, it is necessary to pay attention to operational norms to ensure the safety and stability of the beneficiation process.
