Tungsten ore gravity separation method

Tungsten ore gravity separation method

Tungsten ore is an important metal mineral resource with a high tungsten content, but its mining and beneficiation are also difficult. In the process of tungsten ore beneficiation, gravity separation is required to achieve higher tungsten grade and recovery rate. This article will introduce several common tungsten ore gravity separation methods to help readers better understand tungsten ore gravity separation technology.

1、 Heavy medium selection method

The heavy medium separation method is a commonly used method in tungsten ore gravity separation. The principle of this method is to use media of different densities to separate the ore, thereby achieving the goal of gravity separation. In the heavy medium selection method, commonly used media include water, heavy medium, and gas. The water dense medium separation method is the most common one, which uses the buoyancy of water to separate the ore. The principle of heavy medium gravity separation is to use the density difference of heavy medium (such as heavy liquid) to separate ores. The gas gravity separation method utilizes the buoyancy of bubbles to separate the ore.

2、 Gravity selection method

Gravity separation method is a commonly used method in tungsten ore gravity separation. The principle of this method is to separate the ore using gravity. In the gravity separation method, commonly used equipment includes gravity concentrators, spiral concentrators, centrifugal concentrators, etc. Among them, gravity concentrator is the most common type, which uses gravity to separate ore and has good separation effect.

3、 Flotation method

Flotation method is a commonly used method in tungsten ore gravity separation. The principle of this method is to utilize the differences in physical and chemical properties of mineral surfaces to separate minerals. In the flotation method, commonly used reagents include collectors, foaming agents, and adjusting agents. Among them, the function of the collector is to adsorb the mineral surface, causing it to come into contact with bubbles and rise; The function of foaming agent is to generate bubbles, causing them to come into contact with minerals and rise; The function of the regulator is to adjust the pH value of the slurry to make it suitable for flotation.

4、 Magnetic separation method

The magnetic separation method is a commonly used method in tungsten ore gravity separation. The principle of this method is to separate minerals by utilizing their different reactions to magnetic fields. In magnetic separation, commonly used equipment includes dry magnetic separators and wet magnetic separators. Among them, dry magnetic separators are suitable for the beneficiation of dry ores, while wet magnetic separators are suitable for the beneficiation of wet ores.

Summary:

tungsten ore gravity separation is a very important part of the tungsten ore beneficiation process. This article introduces several common tungsten ore gravity separation methods, including heavy medium separation, gravity separation, flotation, and magnetic separation. In practical applications, it is necessary to select appropriate gravity separation methods based on the properties of the ore and the requirements of beneficiation, in order to achieve the best separation effect.
