Net-shaped magnetism gathering medium for high-gradient magnetic separation and medium box

Abstract

The invention relates to a net-shaped magnetism gathering medium for high-gradient magnetic separation and a medium box, and belongs to the technical field of chemical engineering, environment, materials and mineral processing. The medium is of a net structure formed by weaving high-permeability metal wires, the wire diameter ranges from 0.001 mm to 1 mm, the ratio of the wire diameter to the hole width ranges from 1 to 10, standardized mesh modules of different specifications and a fixing frame are combined for adjustment, and the medium can adapt to different mineral particle sizes and magnetic characteristics. The medium can be mounted in a medium box of the magnetic separator in a single-layer, double-layer or multi-layer stacking manner, and a uniformly distributed high-gradient magnetic field is formed through a woven structure, so that high-efficiency capture of fine weakly magnetic particles is realized. Compared with an existing medium structure, the medium structure has the advantages of being diversified in structural parameter, uniform in magnetic force distribution, high in anti-blocking performance and the like, and is suitable for recovery of weak magnetic minerals such as fine-particle and micro-fine-particle lepidolite ore, ilmenite, wolframite and red mud and iron and titanium removal of ultra-pure materials such as lithium source materials, electronic-grade quartz, kaolin and water glass.
