Seashore zirconium titanium sand ore is an important mineral resource that can be used to manufacture high-quality ceramics, glass, chemical and other products. However, there are a large number of impurities such as iron, aluminum, calcium, etc. in the coastal zirconium titanium sand ore, which can have a negative impact on product quality. Therefore, purification and impurity removal are essential steps in the processing of seaside zirconium titanium placer ore. This article will introduce several methods for purifying and removing impurities from coastal zirconium titanium placers.
1、 Physical methods
1. Reselection method
The gravity separation method is a commonly used method for purifying and removing impurities from coastal zirconium titanium placers. This method utilizes the difference in settling speed of minerals in media with different densities to separate minerals of different densities. The gravity concentration method is applicable to the situation where the mineral particle size is large and the density difference is large.
2. Magnetic separation method
Magnetic separation method is a method that utilizes the response of minerals to magnetic fields to achieve separation. This method is applicable to situations where minerals contain magnetic substances. Magnetic separation can effectively remove impurities such as iron from minerals.
2、 Chemical methods
1. Leaching method
Leaching method is a method of using chemical reactions to dissolve useful substances in minerals. This method is applicable to situations where minerals contain substances that are easily soluble in water or acid. The leaching method can efficiently extract useful substances from minerals, but it also dissolves some impurities.
2. Oxidation-reduction method
The oxidation-reduction method is a method of reducing useful substances in minerals by Redox. This method is applicable to situations where minerals contain substances that are prone to oxidation and reduction. The redox method can efficiently extract useful substances from minerals and has a certain removal effect on some difficult to remove impurities.
3、 Biological methods
1. Microbial leaching method
Microbial leaching is a method that uses microorganisms to dissolve useful substances in minerals. This method is applicable to situations where minerals contain substances that are easily decomposed by microorganisms. Microbial leaching method can efficiently extract useful substances from minerals, and also has a certain removal effect for some impurities that are difficult to remove.
2. Plant adsorption method
Plant adsorption method is a method of utilizing plants to adsorb useful substances from minerals. This method is applicable to situations where minerals contain substances that are easily adsorbed by plants. The plant adsorption method can efficiently extract useful substances from minerals and has a certain removal effect on some difficult to remove impurities.
In summary, the purification and impurity removal methods for seaside zirconium titanium sand ore include physical methods, chemical methods, and biological methods. Different methods are applicable to different mineral types and impurity levels. In practical applications, it is necessary to select appropriate methods based on specific circumstances and combine multiple methods for comprehensive utilization to achieve the best purification and impurity removal effect.
