Flotation Sulfur Froth

Froth flotation means forming a froth of particles bearing minerals by a flotation action then recovered those particles selectively from the bulk a particle in water can adhere to an air bubble if its surface is hydrophobic then it can upward to the surface with other particles that form the froth flotation is the technique used to
