Enhancement of coal flotation using impact flow ...

Sep 10, 2020  The flotation results of coal for different impact velocities are shown in Fig. 9. As shown in Fig. 9, the concentrate yield of coal using impact flow conditioning was significantly higher than that without conditioning. Moreover, the concentrate yield increased with the increase in the impact velocity from 1 to 4 m/s, after which it decreased ...

Coal cleaning by froth flotation - Iowa State University

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.
