Zirconium titanium sand is an important metal mineral resource widely used in fields such as aerospace, nuclear industry, electronics, and chemical industry. The pre selection and enrichment of zirconium titanium sand is an important step in improving ore grade and recovery rate. This article will introduce the pre selection and enrichment methods of zirconium titanium sand.
1、 Magnetic separation method
Magnetic separation method is one of the commonly used methods for pre concentration of zirconium titanium sand. By using a magnetic separator to separate magnetic minerals from non magnetic minerals, the grade and recovery rate of zirconium titanium sand can be improved. The operating steps of magnetic separation method are as follows:
1. Crush the zirconium titanium sand ore to an appropriate particle size.
2. Separate minerals with different particle sizes through a vibrating screen.
3. Conduct magnetic separation of the ore through a magnetic separator to separate magnetic and non magnetic minerals.
4. Collect magnetic minerals and perform drying, weighing, and other processing.
5. Collect non magnetic minerals and perform subsequent processing.
2、 Heavy medium method
The heavy medium method is another commonly used method for pre selection and enrichment of zirconium titanium sand. By separating minerals with different densities through heavy media, the grade and recovery rate of zirconium titanium sand can be improved. The operating steps of the heavy medium method are as follows:
1. Crush the zirconium titanium sand ore to an appropriate particle size.
2. Separate minerals with different particle sizes through a vibrating screen.
3. Separate the ore through a heavy medium to separate minerals with different densities.
4. Collect the minerals in the heavy medium and perform drying, weighing, and other processing.
5. Collect minerals from non heavy media and perform subsequent processing.
3、 Flotation method
The 
flotation method is another commonly used method for pre selection and enrichment of zirconium titanium sand. By using a flotation machine to separate organic matter and minerals, the grade and recovery rate of zirconium titanium sand can be improved. The operation steps of the flotation method are as follows:
1. Crush the zirconium titanium sand ore to an appropriate particle size.
2. Separate minerals with different particle sizes through a vibrating screen.
3. Float the ore through a flotation machine to separate organic matter from minerals.
4. Collect and dry the flotation minerals, weigh them, etc.
5. Collect the minerals that have not been flotation and carry out subsequent processing.
In summary, there are three commonly used methods for preconcentration and enrichment of zirconium titanium sand: magnetic separation, heavy medium method, and flotation method. Different methods are suitable for different zirconium titanium sand ores, and the specific selection of which method needs to be determined based on the actual situation.
