flotation separation of sand and gold

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Apr 18, 2016 There were two general cyanidation flowsheets; sand leaching and all sliming. The latter ultimately has almost completely replaced sand leaching. With the advent of flotation and the fact that gold either free or finely disseminated in pyrite, etc., could be floated, many possibilities opened up for the treatment and concentration of gold ores.
