silver ore gravity concentration

  • Gravity Concentration . Gekko

    Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental.
