Mineral processing methods for perovskite

Perovskite is an important mineral resource widely used in metallurgy, chemical industry, electronics, optoelectronics, and other fields. The beneficiation method of perovskite is of great significance for improving the grade and recovery rate of the ore. This article will introduce several commonly used perovskite beneficiation methods, as well as operating steps and application situations.

1、 Reselection method

Gravity concentration method is a common mineral processing method for perovskite. Its principle is to use the density difference between perovskite and other minerals for separation. The operating steps of the reselection method are as follows:

1. Ore crushing: Crushing the raw ore, usually using jaw crushers and cone crushers.

2. Grinding: Grinding the crushed ore, usually using ball and rod mills.

3. Gravity separation: The ground ore is subjected to gravity separation, usually using a heavy medium separator and a centrifugal separator.

4. Desliming: The carefully selected perovskite is deslimed, usually using a dewatering screen and a desliming cyclone.

The advantage of the gravity separation method is that it is suitable for various types of perovskite and can effectively improve the grade and recovery rate of the ore. But its disadvantage is that the equipment investment and operating costs are high.

2、 Flotation method

Flotation method is a commonly used perovskite beneficiation method, which utilizes the buoyancy difference between perovskite and other minerals for separation. The operation steps of the flotation method are as follows:

1. Ore crushing: Crushing the raw ore, usually using jaw crushers and cone crushers.

2. Grinding: Grinding the crushed ore, usually using ball and rod mills.

3. Flotation: Flotation of ground ore, usually using flotation machines and air flotation machines.

4. Desliming: The flotation perovskite is deslimed, usually using a dewatering screen and a desliming cyclone.

The advantage of flotation method is that it has low equipment investment and operating costs, making it suitable for large-scale production. But its disadvantage is that it has poor adaptability to minerals and is only suitable for specific types of perovskite.

3、 Heavy floating combined method

The combined gravity flotation method is a perovskite beneficiation method that combines gravity separation and flotation. Its principle is to separate perovskite and other minerals based on their density and buoyancy differences. The operating steps of the heavy floating combined method are as follows:

1. Ore crushing: Crushing the raw ore, usually using a jaw crusher and a cone crusher.

2. Grinding: Grinding the crushed ore, usually using ball and rod mills.

3. Gravity separation: The ground ore is subjected to gravity separation, usually using a heavy medium separator and a centrifugal separator.

4. Flotation: Flotation is carried out on the selected perovskite, usually using flotation machines and air flotation machines.

5. Desliming: The perovskite after heavy flotation is deslimed, usually using a dewatering screen and a desliming cyclone.

The advantage of the heavy flotation combined method is that it can overcome the shortcomings of a single beneficiation method, improve the grade and recovery rate of the ore. But its disadvantage is that the equipment investment and operating costs are high.

4、 Application situation

The selection of perovskite beneficiation methods should be comprehensively considered based on factors such as ore type, grade, and scale. At present, gravity separation, flotation, and combined gravity flotation methods are widely used in the field of perovskite beneficiation. Among them, the heavy flotation combined method has obvious advantages in improving ore grade and recovery rate, but its equipment investment and operating costs are high, making it suitable for large-scale production. The gravity separation method and flotation method are applicable to various scales of production, but may have poor adaptability for specific types of ores.

In summary, the selection of perovskite beneficiation methods should be comprehensively considered based on the actual situation to achieve the best beneficiation effect.
