Seaside zirconium ore is an important industrial mineral resource. Its main components are zirconia and Zirconium(IV) silicate, which are widely used in aerospace, electronics, ceramics and other fields. However, due to the fact that coastal zircon ore contains more impurity elements, such as titanium, iron, aluminum, etc., some special beneficiation technologies need to be adopted in the process of ore extraction and processing to improve the grade and recovery of zircon.
The seaside zirconium gravity beneficiation technology is a beneficiation technology based on the principle of gravity separation. Its main principle is to separate different density minerals in the seaside zirconium ore by utilizing their different motion characteristics in the gravity field. This technology has the advantages of simple operation, low equipment investment, low energy consumption, and environmental protection, and has become one of the main technologies for coastal zirconium ore beneficiation.
Principle of Seashore Zirconium Gravity Beneficiation Technology

seaside zirconium gravity beneficiation technology is a beneficiation technology based on the principle of gravity separation. The main principle is to utilize the different motion characteristics of minerals with different densities in the gravity field of coastal zirconium ore to separate them. In a gravity field, minerals with high density sink faster, while minerals with low density sink slower. Therefore, minerals with different densities can be separated by adjusting the strength and direction of the gravity field.
The coastal zirconium gravity beneficiation technology mainly includes three methods: heavy medium beneficiation, centrifugal beneficiation, and vibration beneficiation. Among them, heavy medium beneficiation is to use density difference to divide ore into heavy medium and light medium, and then separate the heavy medium from it by gravity separation; Centrifugal beneficiation uses centrifugal force to divide the ore into parts with different densities, and then separates the heavy minerals from them through gravity separation; Vibration beneficiation is the use of vibration to divide ore into parts of different densities, and then separate the heavy minerals from them through gravity separation.
2、 Operating Steps of Seashore Zirconium Gravity Beneficiation Technology
1. Crushing and screening of zirconium ore in the seaside
Firstly, it is necessary to crush and screen the collected coastal zirconium ore for subsequent beneficiation operations. Crushing can be done using equipment such as jaw crushers and cone crushers, and screening can be done using a screening machine.
2. Heavy medium beneficiation
Mix the crushed seaside zirconium ore with heavy medium and place it in the heavy medium beneficiation equipment for beneficiation. The heavy medium beneficiation equipment adopts a density of 1.5-3.5g/cm ³ Such as magnetite powder, graphite, Baryte, etc. After heavy medium beneficiation, the ore can be divided into two parts: heavy medium and light medium, and then the heavy medium can be separated by gravity separation.
3. Centrifugal beneficiation
Mix the crushed seaside zirconium ore with the heavy medium in the centrifugal beneficiation equipment and place it in the centrifugal beneficiation equipment for beneficiation. The centrifugal beneficiation equipment uses a centrifuge to divide the ore into parts with different densities, and then separates the heavy minerals from them through gravity separation.
4. Vibration beneficiation
Mix the crushed seaside zirconium ore with the heavy medium in the vibration beneficiation equipment and place it in the vibration beneficiation equipment for beneficiation. The vibrating beneficiation equipment uses equipment such as vibrating screens and swinging screens to divide the ore into parts with different densities, and then separates the heavy minerals from them through gravity separation.
3、 Application Prospects of Seaside Zirconium Gravity Beneficiation Technology
The seaside zirconium gravity beneficiation technology has the advantages of simple operation, low equipment investment, low energy consumption, and environmental protection, and has become one of the main technologies for seaside zirconium ore beneficiation. With the rapid development of the marine economy, the demand for zirconium ore in coastal areas will be increasing, and the application prospects of gravity beneficiation technology for zirconium ore in coastal areas will also be broader. In the future, the coastal zirconium gravity beneficiation technology will continue to be optimized and improved to meet the needs of different occasions and make greater contributions to the development of the marine economy.
