Methods of concentration of Ores – Gravity Separation.
This magnetic separation method is suitable for metals that are attracted to a magnetised material and are separated from the non-magnetic particles, thereby enhancing the ore concentration. For this method, a magnetic separator is best suited to process iron ores like magnetite, chromite, and manganese, which are magnetic ores. Conclusion

Heavy Media Separation
Heavy media separation (or sink-and-float separation) is a part of the gravity separation process and uses heavy liquids in the separation operation. The primer liquids for density separation include bromoform (2.84 g/cm 3) and diiodomethane (3.31 g/cm 3 ), where heavy particles (heavier than the selected liquid) will sink while light materials ...

Developments in the physical separation of iron ore: magnetic
Based on the magnetic susceptibility values in Table 9.1, iron ore can be divided into two groups, namely, strongly magnetic iron ores, that is, magnetite (72.4% Fe), and weakly magnetic iron ores (oxidized iron ores), that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% Fe ...

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 …

How does a Magnetic Separator Work?
A magnetic separator is made up of a powerful magnet that is either placed or suspended from a ceiling or device. If a tabletop magnetic separator is used, materials or mixtures can simply be passed over it. On the other hand, suspended magnetic separators are often hung over the mixture or material to remove magnetically susceptible impurities ...

If one acts on the other and vise verse then they must be connected. Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. I suspect gravity is a direct result of a magnetic field.
