Coal Flotation SpringerLink

Abstract. Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from run-of-mine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water.
