The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.

Gold Flotation Process, Equipment

2. Flotation: The finely ground ore slurry is mixed with a flotation agent. The flotation agent type and amount will be selected according to the specific ore properties. Send the slurry into the flotation machine. The gold particles will be adsorbed on the air bubbles due to their unique properties, while other minerals will sink to the bottom.
