[0002] According to the physical and chemical properties of different minerals in the ore, after the ore is crushed and ground, gravity separation, flotation, magnetic separation, electrostatic separation, etc. are used to separate the useful minerals from the gangue minerals, and to separate the various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, so as to obtain the raw materials required for smelting or other industries.

[0003] Spiral beneficiation is one of the simple and efficient beneficiation methods. The typical equipment used in spiral beneficiation is the spiral chute. The main structure of the spiral chute is spiral. Its working principle and process are: first, pour the slurry from the top of the spiral chute, and then gradually stratify during the flow along the trough. The heavy mineral particles entering the bottom layer tend to move toward the inner edge of the spiral chute, and the light minerals are thrown to the outer edge of the spiral chute during the rotational motion. Depending on the different densities of the mineral particles, the minerals are separated in the lateral range of the spiral chute.

[0004] In order to improve the recovery rate of fine magnetic minerals, a permanent magnet is generally provided on the outside of the spiral chute. This will cause some of the magnetic minerals to adhere to the inside of the spiral chute, making it difficult to recover the magnetic minerals. Utility Model Content
