Tungsten sand beneficiation technology

Tungsten sand is a common metal ore with a high tungsten content, which is widely used in the manufacturing of tungsten steel, alloys, and other fields. However, the beneficiation process of tungsten sand is relatively complex and requires certain technical means to achieve the best beneficiation effect. This article will introduce the relevant knowledge of tungsten sand beneficiation technology, including its basic principles, process flow, key equipment, and operating steps.

1、 Basic principles of tungsten sand beneficiation technology

The basic principle of tungsten ore beneficiation technology is to separate impurities from tungsten ore through physical and chemical methods, thereby improving the purity and grade of tungsten ore. It is mainly divided into multiple methods such as gravity separation, flotation, magnetic separation, and chemical beneficiation. Among them, gravity separation method and flotation method are currently two widely used methods.

The gravity separation method utilizes the different settling velocities of tungsten sand and impurities under the action of gravity for separation. The basic principle is to mix tungsten ore and water through a hydraulic concentrator, and then separate tungsten sand and impurities through gravity. Tungsten sand has a higher density and faster settling speed, while impurities have a lower density and slower settling speed, thus achieving the separation of tungsten sand and impurities.

The flotation method utilizes the different buoyancy of tungsten sand and impurities under the action of bubbles for separation. The basic principle is to mix tungsten ore and reagents through a flotation machine, and then separate tungsten sand and impurities through the action of bubbles. The agent can change the surface properties of tungsten sand and impurities, causing them to generate different buoyancy under the action of bubbles, thus achieving the separation of tungsten sand and impurities.

2、 Process flow of tungsten sand beneficiation technology

The process flow of tungsten sand beneficiation technology includes multiple stages such as rough selection, cleaning, and recovery. The specific process is as follows:

1. Roughing: After crushing, screening, and other processing of the raw ore, it is sent to a hydraulic concentrator for roughing. During this process, a hydraulic concentrator is used to mix tungsten ore with water, and tungsten sand and impurities are separated by gravity. The separated tungsten sand is sent to the flotation machine for further processing.

2. Cleaning: The roughly selected tungsten sand is sent to the flotation machine for cleaning. During this process, a flotation machine is used to mix tungsten sand with reagents, and the tungsten sand and impurities are separated through the action of bubbles. The separated tungsten sand is sent to the magnetic separator for further processing.

3. Recycling: The cleaned tungsten sand is fed into a magnetic separator for recycling. During this process, a magnetic separator is used to separate tungsten sand and magnetic impurities. The separated tungsten sand is the final product and can be processed in the next step.

Key equipment for tungsten sand beneficiation technology

The key equipment of the tungsten sand beneficiation technology includes various equipment such as hydraulic beneficiation machines, flotation machines, and magnetic separators. These equipment play a crucial role in the tungsten sand beneficiation process.

Hydraulic beneficiation machine is one of the most commonly used equipment in tungsten ore beneficiation. Its main function is to mix tungsten ore with water and separate tungsten sand and impurities through gravity. It has a simple structure, convenient operation, and high efficiency, making it an indispensable equipment in the tungsten sand beneficiation process.

Flotation machine is another commonly used equipment in tungsten sand beneficiation, whose main function is to mix tungsten sand and reagents, and separate tungsten sand and impurities through the action of bubbles. Its structure is complex and the operation is relatively cumbersome, but it can achieve a more efficient separation effect.

Magnetic separator is one of the key equipment used for recovering tungsten sand in tungsten sand beneficiation, and its main function is to separate tungsten sand and magnetic impurities. It has a simple structure, convenient operation, and high recovery efficiency, making it an indispensable equipment in the tungsten sand beneficiation process.

4、 Operation steps of tungsten sand beneficiation technology

The operational steps of tungsten ore beneficiation technology include multiple stages such as raw ore processing, equipment debugging, trial production, and formal production. The specific steps are as follows:

1. Raw ore processing: After crushing, screening, and other processing, the raw ore is sent to a hydraulic concentrator for rough selection. During this process, attention should be paid to factors such as the quality and tungsten content of the raw ore to ensure the smooth progress of the subsequent beneficiation process.

2. Equipment debugging: Before conducting trial production, key equipment such as hydraulic concentrators, flotation machines, and magnetic separators should be debugged to ensure their normal operation and separation efficiency.

3. Trial production: After the equipment debugging is completed, trial production will be carried out. During the trial production process, attention should be paid to the operating status and separation effect of the equipment, and factors such as adjusting parameters and reagent ratios in a timely manner to achieve the best beneficiation effect.

4. Formal production: After passing the trial production, formal production will begin. During the formal production process, attention should be paid to the maintenance and upkeep of the equipment, and factors such as impurities and scale inside the equipment should be cleaned in a timely manner to ensure the long-term stable operation of the equipment and the beneficiation effect.
