Product Overview

Description

 

 

the minerals are basically liberated from the gangue with the useful mineral density over 4g/cm3 and sometimes the minerals are magnetic. Gravity separation is mainly used as rough separation while combination of magnetic separation-gravity serration and magnetic separation-electric separation and floatation separation is adopted for the fine selection of rough concentrate from gravity separation.
