Various Practical Uses of the Magnetic Separator

Dec. 27, 2022

A magnetic separator is a device that uses a magnet to remove impurities and other magnetic materials from metal. Magnetic separators can be used before, during, and after the production of a material and can be adjusted to attract different types of magnetic materials at different intensity levels.

Although its use is almost always industrial in nature, a magnetic separator is used for a wide variety of applications. Magnetic separators can be ferromagnetic or paramagnetic and can vary in size from a table version to a large, heavy drum used in recycling and other manufacturing applications.

How is a magnetic separator used?

A magnetic separator consists of a powerful magnet that is placed or suspended from a ceiling or device. Materials can be passed over a tabletop magnetic separator, while suspended magnetic separators often hangover material to remove its impurities. Magnetic separators can also be cylinders through which objects pass. The material that purifies a magnetic separator can be in the form of parts, a finished product, or even a liquid metal. With this, a magnetic separator is characterized by:

To be an excellent machine to separate magnetic materials from concentrates.

Removes natural magnetic minerals such as magnetite, as well as steel filings from metal processing material and iron particles.

Remove magnetic like gold concentrates, because it allows gold to recover much more easily.

 

Magnetic susceptibility

Magnetic susceptibility is a measure of how susceptible a mineral is to a magnetic field. The higher the magnetic susceptibility, the stronger the force of attraction to a magnetic field. A negative magnetic susceptibility implies the mineral is repelled by a magnetic force.

Minerals have a range of magnetic properties, and are categorized from high to low as:

Both Ferro- and ferrimagnetic minerals have high magnetic susceptibilities, greater than 1,000 x 10-8 m3/kg. These minerals can be sorted with weak barium ferrite magnets. Paramagnetic minerals have lower magnetic susceptibility, in the region of 50 x 10-8 m3/kg, and can be sorted using strong neodymium magnets. Diamagnetic minerals have negative magnetic susceptibility values, in the order of -5 x 10-8 m3/kg, and are repelled by a magnetic force. Diamagnetic minerals report to the non-magnetic fraction of a dry magnetic separator.

Knowing what magnetic properties your minerals contain allows you to more effectively design processes and set up equipment to further concentrate the ore and to discard waste.
