Coal cleaning by froth flotation

When a micro-bubble flotation technique was employed to float Appalachian coal, it produced a cleaner coal product than conventional macro-bubble flotation. A general kinetic model was proposed to represent the rate of flo­ tation of coal. For two Appalachian coals, the model successfully represented the flotation kinetics of uniformly sized coal.
