The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material , such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized
Sep 28, 2014 Magnetic Separation 1. Magnetic separator. Working principle. Construction. Types and Industrial applications. Safety parameters. Question session. 2. A device in which a magnetic field is employed to remove magnetic materials from feed, or concentrate ore, or to selectively remove or separate constituent minerals.
In the magnetic separator, material is passed through the field of an electromagnet which causes the retention or retardation of the magnetic constituent. It is important that the material should be supplied as a thin sheet in order that all the particles are subjected to a field of the same intensity and so that the free movement of individual particles is not impeded.
Oct 22, 2018 F (m) V.K.H.H/R. For a successful separation, the magnetic force F (m) must be able to move the paramagnetic mineral from its natural path immediately after leaving a separator, or lift it from a belt (overcoming gravity) in the case of a Disc type magnetic separator.
