The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

Dec 20, 2018· The flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some gold-bearing pyrite and pyrrhotite, it is suitable for flotation in weak acid pulp medium. Oxygen has an effect on the flotation process of gold-silver sulfide ore oxidized to different degrees.

1 Froth Flotation – Fundamental Principles

Jan 17, 2011· Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second ...

gold ore competitive copper ore flotation machine

Jul 23, 2014· Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
