2. INTRODUCTION Magnetic separators are used to separate either valuable minerals from non-magnetic gangue, e.g. magnetite from quartz, or magnetic contaminants Or other valuable minerals from the non- magnetic values. All materials are affected in some way when placed in a magnetic field, although with most substances the effect is too slight to be …
