Description

technical field

[0001] The invention relates to an iron ore separation method and equipment, in particular to an iron ore dry powder magnetic separation process and equipment. Background technique

[0002] In the existing iron ore wet separation technology, although wet magnetic separation can meet the technical requirements, it requires the factory to be established in a place with sufficient water source, and for the mining area lacking water, it is impossible to use wet magnetic separation to obtain high precision. of iron powder. Contents of the invention

[0003] The purpose of the present invention is to provide an iron ore dry powder magnetic separation process to be used in an anhydrous mining area to obtain qualified iron fine powder with a grade up to 66%.

[0004] Another object of the present invention is to provide an iron ore dry powder magnetic separator to solve the difficult problem of mine development in arid and water-deficient areas.

[0005] The pres...
