Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are.Magnetic Separation - an overview | ScienceDirect TopicsPhysical separation can be summarized as follows: (1) Separation is a dry process; (2) ore crushing is conducted in the mining pit; and (3) ore crushed to −25 mm is . The optimal conditions of Al2O3 extraction were: a 45% concentration of NaOH solution, a CaO-to-RM mass ratio of 0.25, and a liquid-to-solid ratio of 0.9.
