Magnetic Separation - an overview ScienceDirect Topics

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 the drum, while the nonmagnetic slurry keeps flowing.

RECENT PROGRESS OF OXYGEN/NITROGEN SEPARATION

2/N 2 separation is a pressure driven process, where the driving force is induced by the difference in pressure between downstream and upstream sides. The membrane used in the gas separation process is generally non-porous layer, so there will be no severe leakage of gas across the membrane due to the membrane porosity [7].
