What is Barite? • Earth
Barite (BaSO4) is a mineral consisting of barium sulfate. It is generally white or colorless, and is the main source of barium. tabling, flotation, and magnetic separation.

The magnetic separation of barite is mainly based on the surface magnetic difference between barite and iron oxide minerals. Some barite minerals such as siderite are usually selected.These may be separated from the barite by gravity separation, magnetic separation, and froth floatation. The barite is then either dried and sold as a powder, or processed further for particular applications (Nigeria Geological Survey Agency, 2011). 3.2.

Gravity and Magnetic Separation for Chromite Mineral
1. Strong magnetic tail throwing-shaker sorting process. In this process, a strong magnetic separator is used as the first stage of separation to enrich most of the concentrate and discard the tailings. The first-stage magnetic separation concentrate enters the shaker for sorting. The purpose of this is to improve the grade of the concentrateSometimes more complex beneficiation methods are required, such as heavy media separation, flotation and magnetic separation. Most barite ore requires some upgrading to meet minimum purity or specific gravity levels. Barite mining in the United States occurs predominantly in Nevada at four mines in Elko and Lander counties.Mineral Resource of the Month: Barite EARTH Magazine

Magnetic matrices used in high gradient magnetic separation
High magnetic field gradient is a crucial factor in HGMS process which can be described as a separation process or a deep-bed filtration process in which a magnetic matrix is magnetized and used to bundle the external magnetic field in its vicinity to generate high magnetic field gradient [12].In the presence of strong magnetic field, paramagnetic Magnetic screen is also a kind of magnetic-heavy combined separating equipment. After the effective agglomeration of magnetite in weak magnetic field, the magnetic material is discharged from the screen, gangue and lean intergrowth body are discharged from the screen by special sieve installed in magnetic field, so as to realize 6 Common Magnetic Separation Equipment for Magnetite Separation
