Therefore, the gravity separation method is an ideal method to treat antimony ore. The primary condition for gravity beneficiation is monomer dissociation. For antimony ore beneficiation, the degree of monomer dissociation between antimony ore and waste rock directly affects the effect and beneficiation index of gravity separation.
