  Beneficiation of the gold bearing ore by gravity and flotation

  Abstract. Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and ...

  Handbook of Flotation Reagents: Chemistry, Theory and Practice

  This chapter focuses on treatment methods for gold-bearing ores. Flotation is the best method for recovery of gold from base metal ores and gold-containing PGM (platinum group metal ores. Excluding gravity preconcentration, flotation remains the most cost-effective beneficiation method. During flotation of gold-bearing massive sulphide ores ...
