Background
At present, most of iron ore types have a certain degree of magnetism, so magnetic separation is the most important ore separation method of iron ore, wherein strong magnetic minerals such as magnetite and titanomagnetite are separated by a multi-purpose drum type magnetic separator, and weak magnetic minerals such as hematite limonite, specularite and the like are separated by a multi-purpose vertical ring high-intensity magnetic separator and a flat ring high-intensity magnetic separator.
Magnetite is the most widely utilized iron ore with larger current reserves, and is separated and recovered by a magnetic separator with smaller magnetic field strength due to stronger magnetism. Before entering grinding, magnetite is generally subjected to three-stage or four-stage crushing operation, and each stage of crushing operation is to perform primary dissociation on magnetite ore, so that partial monomer gangue without magnetite is regenerated, and the gangue is subjected to separation and tail-throwing, so that the ore quantity fed into grinding and selecting operation is reduced, the energy consumption and equipment investment of grinding and selecting are reduced, and the economic benefit of a concentrating mill is improved.
