Problems solved by technology

[0003] However, most of the magnetic separation columns on the market are electromagnetic magnetic separation columns, which have disadvantages such as weak magnetic field strength, poor magnetic agglomeration and separation, more electrical failures, unstable operation, large water consumption, and large tailing. For iron ore and other strong magnetic minerals, the grade of the concentrate is limited, and it is not suitable for the selection of weak magnetic refractory iron ores such as hematite, limonite, and siderite.
[0004] Due to the problems of many electrical failures and unstable operation in the electromagnetic magnetic separation column, a permanent magnetic magnetic separation column appeared, but the existing permanent magnetic magnetic separation column device has complex structure, poor magnetic agglomeration and separation, Defects such as large water consumption, large tailing volume, and low production capacity of a single device

Abstract

The invention belongs to the field of magnetic separation columns and particularly relates to a permanent magnetic separation column suitable for strongly or weakly magnetic minerals. Permanent magnetic systems are adopted, the magnetic field intensity can be adjusted within 1,600-16,000 Gs, and an inner permanent magnetic field mechanism and an outer permanent magnetic field mechanism which are in spiral distribution and movement are arranged simultaneously meet the requirement for production of big or small magnetic separation columns; fed water and minerals in a mineral separation chamber conduct inversely spiral upward movements to separate concentrate from tailing more radically, so that the concentrate grade is further improved; concentrate particles conduct obliquely downward slow movement under dual actions of the magnetic field and the dead weight, so that the tailing missing amount is reduced; and the permanent magnetic separation column is simple in structure, stable and reliable, low in water consumption, high in equipment output, and is simultaneously suitable for separation of such strongly-magnetic minerals as magnetite and such weakly-magnetic minerals as hematite, limonite and siderite.

Description

technical field [0001] The invention belongs to the field of magnetic separation columns, and in particular relates to a permanent magnetic separation column suitable for strong magnetic minerals or weak magnetic minerals. Background technique [0002] my country is a country rich in low-poverty and refractory iron ore resources. Low-poverty and refractory iron ore accounts for more than 97% of iron ore resources, and most of them are weak magnetic refractory ores. In recent years, the resources of easy-to-separate iron ore have become less and less. Therefore, people have higher and higher requirements for high-performance enrichment and beneficiation equipment for weakly magnetic and difficult-to-separate iron ore. In order to further reduce the gangue content in the enriched iron ore powder, magnetic separation column beneficiation equipment has appeared on the market. [0003] However, most of the magnetic separation columns on the market are electromagnetic magnetic se...
