Magnetic separation of monazite from mixed minerals
The separation of the three minerals was performed by wet magnetic separation method by applying varying magnetic field intensities (0.11, 0.29, 0.56, 0.82 and 1.08 T). The data obtained for the wet
Magnetic Separation
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9]. A slurry passes by a magnetized drum; the magnetic material sticks to …
Recent developments in magnetic methods of material separation
A significant increase in the magnetic field gradient can be achieved by placing ferromagnetic bodies (such as balls, mesh or steel wool) into the magnetic field of a separator (Frantz, 1937).These bodies (usually called a matrix), generate, when magnetised, a high local field gradient of the magnitude as high as 5 × 10 4 T/m. This …

Magnetic Separation for Mineral Processing & Mining
Magnetic Separation in Mineral Processing. Magnetic separation utilizes powerful magnets to pull out ferrous metal contaminants from a product line, trapping them against the face of the magnet and ensuring they cannot re-enter the product stream. The strength of the magnetic field means that continued product flow, no matter how rapid, will ...
Minerals | Special Issue : High Gradient Magnetic Separation …
Dear Colleagues, Modern high-gradient magnetic separation was initially triggered in the early 1930s. In the recent several decades, it has become one of the key technologies in the exploration of weakly magnetic ores, such as oxide irons, ilmenite, wolframite, and manganese, and in the removal of magnetic impurities form non …
Magnetic and Electrostatic Separation
In mineral processing, low intensity magnetic separation (LIMS) and high intensity magnetic separation (HIMS) are used or WHIMS when carried out wet. The magnetic field of LIMS is ∼1000 gauss using permanent magnets, while the high-intensity units require an electromagnet to reach the higher fields of up to 20,000 gauss 1.

Intensity Magnetic Separator
As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at a …
What are the Advantages and Disadvantages of Magnetic …
Magnetic separation performs poorly with non-magnetic or only weakly magnetic materials like gold and graphite. Using it as the sole method won't effectively process these ores. Thus, magnetic separation applications remain constrained regarding suitable ore bodies. Most mineral separations still require gravity, froth flotation, or other ...

Magnetic susceptibilities of minerals
Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
Magnetic separations
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 …
