Gravity Separation - ScienceDirect

2016-1-1 · The evaluation of the separation method or performance of a gravity separation device is usually based on a sink-float analysis and washability curves. A great many applications of the washability curves are applied to cleaning operations in the coal preparation field (coal washing) so that most reference is made to coal washability curves; however, it must be remembered that the
