Zirconium titanium sand is an important metal mineral resource with broad application prospects. However, the extraction process of zirconium titanium sand is relatively complex and requires multiple methods for sorting. Among them, gravity separation is a commonly used method, and this article will introduce the gravity separation process of zirconium titanium sand ore.
The principle of gravity separation for zirconium titanium sand ore
Gravity separation of zircon and titanium placer is a process of realizing separation under the action of gravity field by using the density difference of different minerals. The density of zircon and Rutile is 4.6g/cm respectively ³ And 3.5g/cm ³， Therefore, in the gravity field, zircon is easier to precipitate than Rutile. By adjusting the strength and direction of gravity field, the separation of zircon and Rutile in zircon titanium sand can be realized.
2、 Equipment for gravity separation of zirconium titanium sand ore
The equipment for gravity separation of zirconium titanium sand ore mainly includes vibrating screens, spiral separators, heavy medium separators, centrifugal separators, and vibrating tables.
1. Vibration screen
Vibration screen is a commonly used coarse sorting equipment that can classify zirconium titanium sand according to particle size. Through the screening effect of the vibrating screen, large particles of zirconium titanium sand and small particles of zirconium titanium sand can be separated, providing a foundation for subsequent sorting.
2. Spiral sorting machine
Spiral sorting machine is a commonly used medium particle size sorting equipment that can sort zirconium titanium sand according to its density. In the spiral separator, zircon and titanium sand are transported to the spiral blades. Due to the density difference between zircon and Rutile, zircon will move outward along the spiral blades, while Rutile will move inward along the spiral blades to achieve separation.
3. Heavy medium sorting machine
The heavy medium sorting machine is a commonly used fine-grained sorting equipment that can sort zirconium titanium sand according to its density. In the heavy medium separator, the density of zircon titanium sand can be changed by adding a certain proportion of heavy medium, so as to realize the separation of zircon and Rutile.
4. Centrifugal sorting machine
Centrifugal sorting machine is a commonly used ultra-fine particle sorting equipment that can sort zirconium titanium sand according to its density. In the centrifugal separator, zircon and titanium sand are transported to the centrifuge, and the separation of zircon and Rutile can be realized through the action of centrifugal force.
5. Vibration table
The vibration table is a commonly used fine-grained sorting equipment that can sort zirconium titanium sand according to its density. On the vibration table, zircon and titanium sand are placed on the vibration table. Through the action of vibration, the separation of zircon and Rutile can be realized.
3、 Operating steps for gravity separation of zirconium titanium sand ore
1. Rough classification
Firstly, the zirconium titanium sand is roughly divided through a vibrating screen to separate larger particles of zirconium titanium sand.
2. Medium size sorting
After coarse separation, zircon and Rutile are separated from zircon and titanium sand by spiral separator with medium particle size.
3. Fine particle sorting
Zircon and Rutile are separated from the medium sized zircon and titanium sand by the heavy medium separator.
4. Ultrafine particle sorting
Zircon and Rutile are separated from the ultrafine zircon and titanium sand by centrifugal separator.
5. Final sorting
Zircon and Rutile are separated from ultra-fine sorted zircon and titanium sand by vibrating table.
4、 Summary
Gravity separation of zircon titanium placer is a common separation method, which can separate zircon and Rutile. In the sorting process, various equipment needs to be used for sorting, including vibrating screens, spiral sorting machines, heavy media sorting machines, centrifugal sorting machines, and vibration tables. By following certain operating steps for sorting, efficient sorting of zirconium titanium sand can be achieved.
