Gravity beneficiation equipment for tungsten iron ore

Tungsten iron ore is an important metal ore, widely used in aerospace, electronics, military and other fields due to its high hardness, high melting point, high density and other characteristics. The mining and beneficiation of tungsten iron ore is a complex and important process, in which gravity beneficiation equipment is a key link.

1、 The role of gravity beneficiation equipment

Gravity beneficiation equipment is a device that utilizes the different properties of materials in the gravity field for separation. Its main function is to separate useful minerals and waste rocks from the ore, thereby achieving the goal of improving ore grade and reducing production costs. In the beneficiation process of wolframite, gravity beneficiation equipment is mainly used to select tungsten minerals from wolframite.

II. Types of Gravity Beneficiation Equipment

There are various types of gravity beneficiation equipment, which can be divided into the following categories based on their working principles and structural characteristics:

1. Gravity concentrator

Gravity concentrator is a type of equipment based on the principle of gravity separation, with its main working component being the inclined plane. The material is subjected to gravity and inertial forces on the inclined plane, thereby achieving separation. Gravity concentrators are usually used to select ores with large particles and large density differences, such as tungsten minerals in wolframite.

2. Centrifugal concentrator

A centrifugal concentrator is a device based on the principle of centrifugal force, and its main working component is a centrifuge. The material is separated by the centrifugal force in the centrifuge. Centrifugal concentrators are usually used to select ores with small particles and small density differences, such as iron minerals in iron ores.

3. Flotation machine

A flotation machine is a device based on the principle of bubble attachment, and its main working component is a flotation cell. The material is separated by the action of bubbles in the flotation cell. Flotation machines are usually used to select ores with small particles and large density differences, such as copper minerals in copper ores.

3、 Operating steps of gravity beneficiation equipment

The operation steps of gravity beneficiation equipment mainly include the following aspects:

1. Preparation work

Before using gravity beneficiation equipment, it is necessary to inspect and maintain the equipment to ensure that it is in normal working condition. At the same time, it is also necessary to crush and screen the ore for further beneficiation operations.

2. Adjust device parameters

Before using gravity beneficiation equipment, it is necessary to adjust the parameters of the equipment based on the properties of the ore and beneficiation requirements, such as slope angle, water flow rate, flotation agent dosage, etc.

3. Conduct beneficiation operations

After adjusting the equipment parameters, the processed ore is put into the gravity beneficiation equipment for beneficiation operations. During the operation process, it is necessary to adjust the equipment parameters in a timely manner based on the reaction situation of the equipment to achieve the best beneficiation effect.

4. Cleaning equipment

After the beneficiation operation is completed, it is necessary to clean the gravity beneficiation equipment for the next use. At the same time, it is also necessary to treat the waste generated during the beneficiation process to meet environmental requirements.

4、 Conclusion

Gravity beneficiation equipment is an important link in the process of tungsten iron ore beneficiation, and its beneficiation effect directly affects the ore grade and production cost. When using gravity beneficiation equipment, it is necessary to select appropriate equipment and operating parameters based on the properties of the ore and beneficiation requirements, in order to achieve the best beneficiation effect. At the same time, it is also necessary to conduct regular inspections and maintenance of the equipment to ensure that it is in normal working condition.
