  • The Gravity Separation Methods Used To Process Gold?

    Gravity separation is one of the common methods for gold extraction, which uses different specific gravity of materials and different settlement velocity in the medium to carry out stratified separation. Generally, when gold mostly exists in the form of monomer natural gold, the density difference between gold and gangue is large, it is more effective and economical for gold separation.
