FIELD: separating solid materials.
SUBSTANCE: method comprises using cross-linking agents, such a CaCl2 and NaCl in the ratio of 3:1 and carbonate as a depressor. The condition of dispersed system is stabilized by allowing the system to be calm and mixing the pulp. The device comprises connected in series units for disintegrating and classifying, floating units for basic flotation, floating unit for raw processing, and granulator for producing pellets of carbonate concentrate. The device is provided with units for preparing solutions of cross-link agent and their supply to disintegrating process and units for stabilizing pulp condition.
EFFECT: enhanced efficiency.
