Magnetic separation - Wikipedia

Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...

Magnetic Separators . When differences in specific gravity are not great enough to separate two or more materials, it is time to exploit other physical properties to produce concentrates. Magnetic susceptibility is often the next criteria considered for minerals separation. There are three classes of minerals:

Magnetic Separation Method - Mineral Processing & Metallurgy

Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser (though noticeably) affected are known as ...

Magnetic Separation | Hazen Research

Magnetic Separation Concentration of iron ore with low-intensity magnetic separators has been used for decades in the recovery of magnetite. While gravity separation and froth flotation are two important processes for mineral beneficiation, other methods can be used to concentrate minerals and separate them from gangue and each other.

Mineral processing | metallurgy |

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

(DOC) Magnetic separation | Hamza Achache -

Introduction: Magnetic separation exploits the physical properties of the ore components using the ability of a material to react to a magnetic field. This property is also known as magnetic susceptibility. Compared to gravity separation, this method use factors that are intrinsic to a specific material.

Magnetic separation: A review of principles, devices, and ...

The principle of operation of magnetic separation devices is the interaction between magnetic forces and competing gravitational, hydrodynamic, and interparticle forces within the magnetic separator. Without resort to a detailed analysis of the separation process, an understanding of the characteristics of magnetic separators is possible by ...
