Description

Technical Field

[0001] The utility model relates to the field of rough processing of mineral production, in particular to a system for recycling and reusing treated water in the process of mineral production. Background Art

[0002] Heavy medium separation is a method of separating mineral particles according to their specific gravity in a medium with a specific gravity greater than that of water. That is, the minerals with different specific gravities are separated from each other in a straight flow or two-phase fluid by using the floating and sinking principle. The specific gravity of the separation medium used is between the specific gravity of the high and low specific gravity mineral particles to be separated. The mineral particles with a small specific gravity float up, while the mineral particles with a large specific gravity sink, thus achieving the purpose of separation.

[0003] A large amount of clean water is required as the dressing medium in heavy medium beneficiation. The amount of processed water used is very large, so water is generally recycled as much as possible.
