Abstract of the Disclosure A method of comminuting and activating minerals and ores that can undergo flotation or are enriched by flotation, hearth washing, tub washing, heavy fluid separation, magnetic separation, electrostatic separation and the like and which have undergone preliminary comminution to a suitable grain size, preferably smaller than 7-10 mm, and if necessary, have been dried to give a residual moisture content of less than 8-10%, comprising the step that the materials to be treated are subjected to comminution during which at the same time by infusion of energy using mechanical impacting or beating a reproducible change occurs in the fine structure and thus activation in the sense of improved separation during flotation or subsequent smelting of the prepared ores in comparison with starting materials comminuted in the usual way, e.g. in ball mills
