Concentration of Ores – Study Material for IIT JEE ...

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.

Ore & Mineral Concentration Processing Equipment - Mineral ...

Gravity separation is a long-standing beneficiation method. Due to its simplicity, low cost, and growing development, the gravity separation method is still the main beneficiation method for tungsten tin ore and coal. It has also been widely used in the selection of certain non-ferrous metals, ferrous metals, precious metals and non-metallic ores.
