Titanium sand is an important mineral resource, which is widely used in aviation, aerospace, military, shipbuilding, chemical and other fields. However, due to the uneven distribution, low content, and difficulty in extracting titanium sand resources, titanium sand beneficiation technology has always been one of the difficulties in the mining industry. This article will introduce the basic principles, commonly used methods, and operational steps of titanium sand beneficiation technology.
1、 Basic principles of titanium sand beneficiation technology
Titanium sand mainly contains elements such as titanium dioxide, iron, aluminum, and silicon, among which titanium dioxide is the main component in titanium sand. The basic principle of titanium sand beneficiation is to separate useful elements such as titanium dioxide from titanium sand using different beneficiation methods based on the differences in physical and chemical properties of each element in titanium sand, in order to improve the grade of titanium sand.
2、 Commonly used titanium sand beneficiation methods
1. Reselection method
Gravity concentration method is one of the main methods for titanium sand beneficiation. Its basic principle is to use the density difference of each element in titanium sand, and use gravity beneficiation equipment, such as gravity concentrator, spiral concentrator, to separate heavy minerals and light minerals from titanium sand. Heavy minerals mainly contain elements such as titanium dioxide and iron, while light minerals mainly contain elements such as silicon and aluminum. The gravity separation method can improve the grade of titanium dioxide in titanium sand and enhance its utilization value.
2. Magnetic separation method
Magnetic separation method utilizes the magnetic properties of iron minerals in titanium sand and uses magnetic separation equipment such as wet magnetic separators and dry magnetic separators to separate iron minerals from titanium sand. The magnetic separation method can reduce the content of iron element in titanium sand and improve the grade of titanium dioxide in titanium sand.
3. Flotation method
The flotation method utilizes the specific gravity and hydrophilicity of various elements in titanium sand, and uses flotation equipment such as flotation machines and air flotation separators to separate useful elements from titanium sand. The grade of titanium dioxide in titanium sand can be improved by flotation method.
3、 Operating steps for titanium sand beneficiation
1. Crushing and grinding of titanium sand
The original titanium sand is processed through crushing, grinding, and other processes to achieve a certain particle size, preparing for subsequent mineral processing work.
Using gravity beneficiation equipment, such as gravity concentrators and spiral concentrators, to separate heavy and light minerals from titanium sand.
3. Magnetic separation
Using magnetic separation equipment, such as wet magnetic separators and dry magnetic separators, to separate iron minerals from titanium sand.
Using flotation equipment such as flotation machines and air flotation separators to separate useful elements from titanium sand.
Select the titanium sand after beneficiation to meet certain grade and quality requirements.
Titanium sand beneficiation technology is one of the important means to improve the grade and utilization value of titanium sand. The commonly used titanium sand beneficiation methods include gravity separation, magnetic separation, flotation, etc. When conducting titanium sand beneficiation operations, it is necessary to carry out scientific and reasonable operation steps based on the characteristics of titanium sand and the principles of beneficiation methods, in order to achieve the best beneficiation effect.Titanium sand beneficiation technology
