This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
