The separation of chromite ore with lowest particle size fraction was done using Mozley mineral separator followed by the magnetic separation of the sink product by magnetic separator. The results obtained revealed about 77% of the total material containing 300 μm particle size, 52% ˂ 212 μm and 17% below 75 μm.
Several attempts have been made by different researchers and technologists to understand the separation behavior of particles in each of these separators treating different types of para-magnetic minerals. Despite all these efforts, these separators are yet to find widespread applications to treat different para-magnetic minerals.

The first SLon-2500 vertical ring-pulsating high gradient magnetic separator was designed and built up in 2006. It was installed at the tails dam of Hai Nan Iron Mining …
Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for …
This study aimed at the investigation of the effect of colloidal magnetic particles on the magnetic separation of iron ore tailings (IOT). For this, the synthesis and characterization of bare iron, iron-dextran, and iron-oleate magnetic particles is reported. FTIR spectra confirmed that the synthesized particles were composed by magnetite.
Finally, the magnetic component of the roasted ore can be recovered by magnetic separation after being liberated from gangue minerals. Many pilot-scale suspension magnetizing roasting and magnetic ...
Magnetic separation experiments of iron ore ultrafines validated the molecular-level analyses meeting experiment–theory nexus. Abstract. Magnetic nanoparticles have diverse scientific and technological applications, as their properties can be tuned accordingly. An example is the selective magnetic coating technique for the selective ...
The widely used method is using a magnetic separator since the iron ore is a material that is strongly attracted by magnetic force. In contrast, the impurity material is repelled by magnetic ...
