The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated. Magnetite content obtained by laboratory techniques varies between 2.92 and 0.11 wt%, with 1.15 wt% …
external applied magnetic field is an important factor; it is the matrix that provides the potential force separation [12-13]. Figure 3, illustrates the relationship between the magnetic field strength and the magnetic separation efficiency of the sample. Maximum separation at certain magnetic field could be attained.

Magnetic Separation 2.1 Introduction The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three main categories, namely diamagnetic, paramagnetic, and ferromagnetic.
Magnetic separation technology is a physical separation method that uses the differences in magnetism between matter to separate them from each other by different motion behaviors in a non-uniform magnetic field. It is highly efficient, green, and environmentally friendly, with little change in the physical and chemical properties of raw …

Conventional magnetic separation is to separate minerals according to their natural magnetism. In addition, in some cases, in order to improve the efficiency of separation, it is possible to change the magnetism of minerals or take some special methods to make the mineral separation more effective, such as magnetization roasting …
This type of magnetic separator is also known as a rotary magnetic belt separator and is always used in traversing operation – for a high extraction of ferromagnetic materials. It is also possible to use stronger magnetic forces with this sorting machine to separate weakly magnetic materials like stainless steels.

Magnetic separation is a process that uses magnets to separate magnetic materials from non-magnetic ones in a mixture. This technique takes advantage of the varying magnetic properties of different substances. The primary component involved in this process is the magnetic separator, a device designed to attract and separate magnetic materials ...
In this regard, the physics of magnetic separation at the microscale is not unlike that of gravitational sedimentation, or sedimentation in a centrifugal field, in that the range of separation is bounded at the small particle size limit by the randomizing effect of thermal motion, and also strongly depends on the separation-specific property of the …
