Titanium sand refers to sand containing titanium, which is an important metal material widely used in aviation, aerospace, military, chemical, pharmaceutical and other fields. The titanium sand beneficiation method refers to the process of extracting titanium elements from titanium sand through a series of physical and chemical methods. This article will introduce several common titanium sand beneficiation methods.
1、 Reselection method
The gravity separation method is a method of separating titanium minerals from other minerals by utilizing the gravity difference between titanium minerals and other minerals in titanium sand. The gravity separation method requires pre-treatment such as crushing, screening, and flotation of titanium sand, and then placing the titanium sand into a gravity separator to separate titanium minerals from other minerals through gravity. This method is suitable for situations where the gravity difference between titanium minerals and other minerals is significant.
2、 Magnetic separation method
Magnetic separation method is a method of separating titanium minerals from other minerals by utilizing the magnetic differences between titanium minerals and other minerals. The magnetic separation method requires pre-treatment such as crushing, screening, and flotation of titanium sand, and then placing the titanium sand into a magnetic separator to separate the titanium mineral from other minerals through magnetic action. This method is suitable for situations where there is a significant difference in magnetic properties between titanium minerals and other minerals.
3、 Flotation method
The flotation method is to separate titanium minerals from other minerals by making use of the difference in density and wettability between titanium minerals and other minerals. The flotation method requires pre-treatment such as crushing and screening of titanium sand, and then placing the titanium sand into a flotation machine to separate titanium minerals from other minerals through bubble action. This method is suitable for the case where the density and wettability of titanium minerals differ greatly from other minerals.
4、 Chloride process process
Chloride process is a method that converts titanium element in titanium sand into titanium chloride, and then separates it from other elements through the physical and chemical properties of titanium chloride. The Chloride process process requires the pretreatment of titanium sand, such as crushing and screening, and then the titanium sand reacts with chlorine to generate titanium chloride. Next, titanium chloride is separated through processes such as sublimation and condensation. This method is suitable for situations where the titanium content in titanium sand is high.
V. Sulfuric acid method
The sulfuric acid method is a method of converting titanium elements in titanium sand into titanium sulfate, and then separating it from other elements through the physical and chemical properties of titanium sulfate. The sulfuric acid method requires pre-treatment such as crushing and screening of titanium sand, and then reacting the titanium sand with sulfuric acid to generate titanium sulfate. Next, titanium sulfate is separated through processes such as hydrolysis and precipitation. This method is suitable for situations where the titanium content in titanium sand is low.
To sum up, the titanium sand dressing methods include gravity separation, magnetic separation, flotation, Chloride process, sulfuric acid and other methods. Different methods are applicable to different titanium sand components and contents. In practical applications, it is necessary to choose appropriate methods based on specific circumstances to achieve the best beneficiation effect.
