Magnetic separation method of concentration of an ore

Apr 14, 2021

Mar 13, 2020 Magnetic separation Method By this method, those ores can be concentrated which either contain impurities which are magnetic or are themselves magnetic in nature. For example, the tin ore, tinstone (SnO 2 ) itself is non-magnetic but contains magnetic impurities such as iron tungstate (FeWO 4 ) and manganese tungstate (MnWO 4 )
