Coal cleaning by froth flotation - Iowa State University

2020-10-13  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.

Physical and chemical interactions in coal flotation ...

2003-9-29  Abstract. Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.
