Jig machine beneficiation, inclined flow beneficiation, centrifugal beneficiation, and shaker table beneficiation respectively refer to
what?
Jig machine beneficiation: The process of layering and separation of numerous ore particle mixtures in a vertically varying medium flow according to density differences is called jigging beneficiation. In the process of jigging beneficiation, the medium used can be water or air. When water is used as the sorting medium, it is called water medium jigging or hydraulic jigging; If air is used as the sorting medium, It is called wind jigging.

Slant flow beneficiation: A method of separation that utilizes the difference in the movement of ore particles on the inclined flow of water, known as inclined flow beneficiation. It includes chute beneficiation and shaker beneficiation.
Centrifuge beneficiation: A gravity separation method that utilizes the centrifugal force exerted by fine ore particles in a centrifugal field to greatly exceed gravity, accelerating the settling of ore particles, expanding the difference in settling speed of ore particles with different densities, and thereby strengthening the separation process.
Shake bed beneficiation: A device used for ore sorting on a tilted and wide bed surface, utilizing the asymmetric reciprocating motion of the bed surface and the action of thin layer inclined water flow.

What are the meanings of selectivity, quantity efficiency, and total amount of mismatched substances?
Selectability: Select the difficulty level of the product from the raw materials according to the required quality indicators.
Quantity efficiency: Quantity efficiency is a relative efficiency that refers to the ratio of the actual yield of clean coal to the theoretical yield when the ash content is the same. It is an important indicator in production and technical management. However, the workload of experiments and calculations is relatively large, which cannot guide production in a timely manner.
Total amount of mismatched materials: When sorting or grading materials, the sum of materials mixed with non specified components in each product is called the total amount of mismatched materials.
What are the meanings of magnetic separation, triboelectric separation, dielectric separation, and dielectric constant respectively?
Magnetic separation: A beneficiation method that utilizes the magnetic differences between minerals in an uneven magnetic field to separate different minerals.
Frictional electric selection: Using two minerals to come into contact, collide, and rub against each other, or to cause friction with a feeding trough made of a certain material, to generate charges of different sizes and opposite signs, which are then fed into a high-voltage electric field. Due to the different charging signs of the ore particles, the motion trajectories generated are also significantly different, resulting in the separation of the two minerals.
Dielectric separation: performed in liquid or air media, usually mostly in liquid media.
