Grinding is used to primarily liberate useful minerals and secondarily provide fine ores with a proper particle size for separation. Gaudin [ 9 ] developed a mineral liberation model for breakage, but it considered materials only as cubes of equal volumes in an excessively simplified mineral mosaic relation.

High kinetic stability can be achieved by fine grinding, but such a suspension could not be sufficiently fluid for the ore particles to move freely in their separation. On the other hand, an excess of coarse particles yields a high fluidity of the medium, but such a medium is not stable without a stirring device to prevent settling out.
