FIELD: invention refers to extraction of useful components out of ores at separation of useful fossils.
SUBSTANCE: mode includes process of size reduction of ores in laboratory mill in dry, wet modes and with additives. At that in process of physical impacting they define by calculating-empirical way specific energy wasted on size reduction, measure specific surface of particles after size reduction and calculate specific surface energy of ores according to definite relation.
EFFECT: increases efficiency of process of extraction of useful components out of ores and optimizes working regimes of present apparatus used at stage of preparation of minerals.
