gravity separation of concentrtion of ores


  • Concentration of Ores – Study Material for IIT JEE | askIITians

    ResultThis 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 …
