The Effect of Grinding Media on Mineral Breakage ...
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.
