Zirconium titanium sand mining and selection method

Zirconium titanium sand mining and selection method

Zirconium titanium sand is an important mineral resource widely used in aviation, aerospace, nuclear industry, electronics, chemical and other fields. However, the distribution of zirconium titanium sand in nature is relatively dispersed, and there are many impurities in the ore, so it is necessary to use scientific mining methods for extraction. This article will introduce several common methods for extracting zirconium titanium sand, including gravity separation, magnetic separation, flotation, electrical separation, etc., and elaborate on their operating steps in detail.

1、 Reselection method

The gravity separation method is a commonly used method for extracting zirconium titanium sand, which is based on the separation of zirconium titanium sand and impurities in the ore by gravity. The specific steps are as follows:

1. Crushing and screening of ores. Firstly, the ore is crushed and screened to obtain moderately sized ore particles.

2. Selection of the reselection machine. Feed the ore particles into the gravity separator for sorting, and separate the zirconium titanium sand and impurities based on the different particle sizes and densities.

3. Treatment of selected tailings. The selected tailings will be re selected to improve the grade of zirconium titanium sand.

2、 Magnetic separation method

Magnetic separation is a mining method that utilizes the adsorption of magnetic materials on minerals for separation. Suitable for zirconium titanium sand ores containing magnetic minerals. The specific steps are as follows:

1. Crushing and screening of ores. Same as the re selection method.

2. Selection of magnetic separators. Feed ore particles into a magnetic separator for separation, and separate zirconium titanium sand and impurities based on their magnetic properties.

3. Treatment of selected tailings. Same as the re selection method.

3、 Flotation method

Flotation method is a mining method that utilizes the contact between minerals and bubbles to float up to the liquid surface and separate them. Suitable for zirconium titanium sand ores containing non-metallic minerals such as silicates. The specific steps are as follows:

1. Crushing and screening of ores. Same as the re selection method.

2. Addition of flotation agents. Add the flotation agent to the slurry to make it come into contact with mineral particles and form bubbles.

3. Selection of flotation machines. Feed the slurry into the flotation machine for sorting, and separate zirconium titanium sand and impurities based on the contact between the mineral and bubbles.

4. Treatment of selected tailings. Same as the re selection method.

4、 Electroselection method

Electric separation method is a mining method that utilizes the different electrical properties of minerals in an electric field for separation. Suitable for zirconium titanium sand ores containing minerals with significant differences in electrical properties. The specific steps are as follows:

1. Crushing and screening of ores. Same as the re selection method.

2. Establishment of electric field. Establish an electric field in the beneficiation machine, so that mineral particles are subjected to different electrical forces in the electric field.

3. Selection. Separate zirconium titanium sand and impurities based on the different electrical properties of minerals in an electric field.

4. Treatment of selected tailings. Same as the re selection method.

summary

The methods for mining and selecting zirconium titanium sand include gravity separation, magnetic separation, flotation, and electrical separation. Different mining methods are suitable for different types of ores, and specific mining methods need to be selected based on the physical and chemical properties of the ore. During the mining and beneficiation process, attention should be paid to issues such as ore crushing and screening, sorting machine selection, and tailings treatment to ensure mining and beneficiation efficiency and economic benefits.
