  • Sink and Float Separation Process

    09/06/2016 · In 1928 the deVooys Process was introduced for the separation of shale from coal. This process employs as "medium" a practically stable suspension of barytes and clay in water whose high kinetic stability makes it possible to dispense with stirring devices for maintaining uniformity of suspension. Thus the separation takes place in a quiescent medium—a most important point, since ...
