Abstract

The invention relates to an iron ore dressing system, and belongs to the technical field of ore dressing devices. The iron ore dressing system comprises mills, hydrocyclones and magnetic separators, astock bin is sequentially connected with the primary magnetic separator, a dewatering screen, a pendulum feeder, the first-section mill, the primary hydrocyclone, the primary magnetic separator and the secondary hydrocyclone. The secondary hydrocyclone is connected with the second-section mill and the secondary magnetic separator separately, the secondary magnetic separator is connected with a vibration screen, the vibration screen is connected with the tertiary magnetic separator and the quaternary magnetic separator separately, and the quaternary magnetic separator is sequentially connectedwith the wet type permanent magnetic drum magnetic separator and the electromagnetic high-gradient magnetic separator. The iron ore dressing system is simple in structure, convenient to operate, lowin operation cost, capable of saving energy and environmentally friendly and has remarkable economic benefits.

Description

technical field [0001] The invention relates to an iron ore beneficiation system, belonging to the technical field of beneficiation devices. Background technique [0002] In the existing iron ore beneficiation technology, the crushing adopts three stages and one closed circuit, and the ore grinding adopts three stages closed circuit grinding, reverse flotation, coarse, fine and three sweeping processes. The beneficiation process of the concentrator is mainly the reverse flotation process. The reverse flotation process is to pass the high-frequency fine sieve through desliming magnetic separation, reverse flotation, and drug-removing magnetic separation. In addition, there are heating, stirring, and dispensing. Auxiliary process, final filtration to obtain concentrate. The reverse flotation process is complicated, the process is long, there are many production auxiliary equipment, a large amount of chemicals are consumed, and the production cost is high, which restricts the ...
