    Nov 01, 2019 · Flotation is an electrochemical process, in which mineral surfaces react with reagents in solution to form hydrophobic complexes that impart flotability to the mineral particles. In sulphide minerals flotation, these reactions involve oxidation of some species and reduction of others, resulting in selective adsorption of collector on the mineral surfaces ( Chander, 1988 )
