A Comparison of Coal Beneficiation Methods

Froth Flotation. To conduct a froth flotation test, 200 g pulverized coal (-35 mesh) were added to 2000 ml tap water in a bowl of a laboratory model Wemco Fagergren flotation cell. With the agitator running, the pH of the slurry was lowered below 5 by adding 10 ml acid solution containing 10 vol % concentrated hydrochloric acid.

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

A Kinetic Model for Conventional Flotation of Coal

The U.S. Bureau of Mines has developed a computer model to describe a flotation process. Coal data from conventional flotation has been converted to a simple, two-parameter kinetic model developed by Reuter and van Deventer (-l,2J3. Each set of coal data was represented by two constants, a and P, and an average flotation rate.

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.
