Zirconium titanium sand beneficiation process flow

Zirconium titanium sand is an important mineral resource widely used in aviation, aerospace, electronics, chemical and other fields. Due to differences in quality, the price of zirconium titanium sand also varies greatly. Therefore, studying the beneficiation process of zirconium titanium sand is of great significance for improving the quality of zirconium titanium sand and reducing production costs.

1、 Basic principles of zirconium titanium sand beneficiation

The basic principle of zirconium titanium sand beneficiation is to separate and purify zirconium titanium sand through physical and chemical methods. Zircon titanium sand mainly contains zircon ore, Ilmenite, Magnetite, Rutile and other minerals, of which zircon ore and Ilmenite are the main components of zircon titanium sand. Therefore, effective separation and purification of zircon ore and Ilmenite is the key to zircon and titanium ore dressing.

2、 Process flow of zirconium titanium sand beneficiation

The process flow of zirconium titanium sand beneficiation mainly includes grinding, gravity separation, magnetic separation, and electric separation. Below, we will provide a detailed introduction to the operational steps of each process.

1. Grinding

grinding is the first step in zirconium titanium sand beneficiation, with the aim of grinding the ore to a certain particle size for subsequent gravity and magnetic separation. The main equipment for grinding ore includes ball mills, rod mills, etc. The operating steps for grinding are as follows:

(1) Send the ore into a ball or rod mill for grinding.

(2) Control the grinding time and the particle size of the grinding medium to grind the ore to a certain particle size.

(3) Feed the ground ore into the gravity separator for gravity separation.

2. Reselection

Gravity concentration is the second step of zircon titanium ore dressing, which aims to separate Ilmenite from zircon in the ore. The equipment for re selection mainly includes spiral sorting machines, flotation machines, etc. The steps for reselection are as follows:

(1) The ground ore is fed into a spiral separator or flotation machine for gravity separation.

(2) Ilmenite and zircon are separated according to the density and color of the ore.

(3) The separated Ilmenite and zircon ores are sent to the magnetic separator and the electric separator respectively for further separation and purification.

3. Magnetic separation

Magnetic separation is the third step in zirconium titanium sand beneficiation, with the aim of separating magnetic minerals from the ore. The equipment for magnetic separation mainly includes high-strength magnetic separators, wet magnetic separators, etc. The operating steps for magnetic separation are as follows:

(1) The separated Ilmenite is sent to a high-intensity magnetic separator or a wet magnetic separator for magnetic separation.

(2) Separate magnetic minerals based on the magnetism of the ore.

(3) Send the separated magnetic minerals into the electric separator for further separation and purification.

4. Electrical selection

Electric separation is the final step in zirconium titanium sand beneficiation, with the aim of separating non magnetic minerals from the ore. The main equipment for electrical separation includes electrostatic sorting machines, high-voltage electrical sorting machines, etc. The operation steps of electric selection are as follows:

(1) Feed the separated zircon ore and magnetic minerals into an electric separator for electric separation.

(2) Separate non magnetic minerals based on the electrical properties of the ore.

(3) After the above process flow, the final product of zirconium titanium sand is obtained.

Optimization of zirconium titanium sand beneficiation process flow

Although the process flow of zirconium titanium sand beneficiation is relatively mature, there are still some problems. For example, the efficiency of magnetic and electrical separation is not high, and the quality of products is unstable. Therefore, it is necessary to optimize the process flow of zirconium titanium sand beneficiation.

1. Optimize the process parameters of magnetic and electrical separation to improve efficiency and quality.

2. Adopting new beneficiation equipment, such as high gradient magnetic separators and electronic separators, to improve beneficiation efficiency and quality.

3. Strengthen the analysis and research of raw materials, and develop more scientific and reasonable beneficiation plans.

4. Strengthen monitoring and control of the beneficiation process to avoid problems during production.

In summary, the zirconium titanium sand beneficiation process is a complex process that requires multiple physical and chemical methods for separation and purification. By optimizing the beneficiation process, the quality of zirconium titanium sand can be improved and production costs can be reduced, thereby better meeting market demand.
