Zircon sand selection technology

Zircon sand selection technology

Zircon sand is a high-purity inorganic material with very high chemical stability and mechanical strength, widely used in industries such as ceramics, electronics, aerospace, etc. In the production process of zircon sand, beneficiation is a very important step, and the quality of beneficiation directly affects the quality and performance of zircon sand. This article will introduce some zircon sand selection techniques to help you better understand this process.

1、 The beneficiation principle of zircon sand

The main components of zircon sand are Zirconium dioxide and silica, and their specific gravity is very close. Therefore, during the beneficiation process, it is necessary to separate them by physical methods. The commonly used methods currently include gravity separation, heavy medium method, flotation method, etc. Among them, gravity separation is the most commonly used method, which uses the density difference between zircon sand and other minerals to separate them through hydraulic concentrators and other equipment.

2、 Beneficiation steps of zircon sand

1. Crushing: First, the raw ore needs to be crushed, usually using equipment such as jaw crushers and hammer crushers.

2. Grinding: Grinding the crushed ore, usually using equipment such as ball mills and roller mills.

3. Beneficiation: The ore that has been ground is beneficiated, usually using equipment such as hydraulic concentrators and heavy media concentrators.

4. Regrinding: Regrinding the ore after beneficiation to improve grinding fineness and beneficiation efficiency.

5. Magnetic separation: Magnetic separation is performed on the finely ground ore to remove magnetic minerals from it.

6. Screening: The magnetically separated ore is screened to separate different particle sizes of zircon sand.

3、 Mineral processing equipment for zircon sand

1. Hydraulic beneficiation machine: A hydraulic beneficiation machine is a type of equipment that uses the principles of hydraulic mechanics to separate ores. The advantages of hydraulic concentrators are simple equipment, convenient operation, and suitable for occasions with small ore dressing volume.

2. Heavy medium beneficiation machine: Heavy medium beneficiation machine is a device that uses heavy media to separate ores, which utilizes the difference in the specific gravity of minerals in the heavy media. The advantage of a heavy medium beneficiation machine is its good beneficiation effect and suitability for occasions with large beneficiation volumes.

3. Flotation machine: A flotation machine is a device that uses bubbles to float minerals for separation. It is suitable for occasions with finer particle size and more types of minerals in mineral processing.

4、 Precautions for beneficiation of zircon sand

1. During the beneficiation process, it is necessary to ensure the normal operation of equipment, especially equipment such as hydraulic beneficiation machines, which should be regularly inspected and maintained.

During the beneficiation process, it is necessary to strictly control the feed volume and water flow rate of the ore to ensure the beneficiation effect.

During the beneficiation process, attention should be paid to controlling the grinding time and the quality of the grinding medium to ensure the beneficiation effect and the quality of zircon sand.

4. The ore after beneficiation needs to undergo magnetic separation and screening treatment to separate zircon sand with different particle sizes.

5、 Conclusion

Mineral processing is a very important step in the production process of zircon sand, and its quality directly affects the quality and performance of zircon sand. This article introduces some techniques and precautions for selecting zircon sand, hoping to be helpful to you. In actual production, it is also necessary to choose suitable beneficiation equipment and methods based on specific circumstances to ensure the quality and yield of zircon sand.
