Description: Mica is one of the most widely distributed rock-forming minerals. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding electrodes, plastic, electrical insulation, papermaking, rubber, pearlescent pigments and other chemical industry. The beneficiation technology of mica contains the hand selected, friction selection, shape selection, flotation and air separation. Here, we will discuss the mica beneficiation technology process. The following is the wonderful discussion's specific content.

• Part 1:

The hand selected is the old beneficiation technology. It has the advantages of simple operation, and no need of complex equipment. The working condition is not limited. It is the most free beneficiation method.

Part 2:

I don't agree with you. The hand selected has been eliminated. It has been unable to meet the demand of modern social development. As far as I know, the friction selection is a good beneficiation technology. The frictional separation equipment has a lot, such as, the metal inclined plate separator, spiral classifier, the inclined plate separator with a guide plate etc. Among them, the spiral classifier is a good choice.

Part 3:

The frictional separation is a good method. But I think the shape selection is a high efficiency way. Shape separation often uses the multilayer sieve. The first layer sieve is the strip shape, and the second layer is the square shape. Mica flake goes easily through the sieve seam, but gangue is not easy passing through screen. This method has the advantages of simple process, less equipment investment, high production capacity, and high separation efficiency, which are widely used in mica mine.

Part 4:

I agree with you. But for separating the fragmental mica, the flotation is the best choice. Before beneficiation, it needs to remove the mud. This beneficiation technology has a high recovery rate. The concentrate grade is high.

Part 5:

Although you are right, we can't forget the air separation. In the early of 80s, foreign countries adopt air separation to make a great progress. There has been a lot of successful examples. It is mainly used for separating coarse mica and cereal shoots selected.
