Abstract

The invention discloses a preparation method of a composite magnetism-gathering medium for a horizontal ring type high-gradient high intensity magnetic separator. The composite magnetism-gathering medium is formed by compounding ultra-pure ferritic stainless steel and industrial pure iron, wherein the composite material is subjected to surfacing degreasing, welding, rolling and cooling to prepare the high intensity magnetic separation magnetism-gathering medium. The tooth-shaped magnetism-gathering medium prepared by the composite material has the advantages of being low in preparing cost, high in magnetic field gradient, long in service life and the like, and is capable of increasing the metal recovery rate and reducing the discharging amount of the tailings in the high intensity magnetic separation process.

Description

technical field [0001] The invention belongs to the field of composite functional materials, and relates to a preparation method of a composite magnetic gathering medium used in a flat-ring high-speed magnetic separator. Background technique [0002] The flat-ring high-gradient strong magnetic separator is widely used in the process of processing weak magnetic fine-grained minerals, and the core component of the flat-ring high-gradient strong magnetic separator is a tooth-shaped magnetic gathering medium, which is machined from ferromagnetic metal materials It is prepared; under the alternating action of an external magnetic field, the ferromagnetic and tooth-like structure of the material is used to improve the magnetic field gradient for mineral separation. [0003] During the use of the strong magnetic separator, with the repeated use of the slurry circulating water, the corrosive ions in the slurry gradually accumulate, so that the magnetic gathering medium of the tooth ...
