FIELD: mining.
SUBSTANCE: invention relates to field of flotation enrichment of beryllium-containing ores. Method includes treatment of pulp by regulators and collector, main and cleaner procedures of flotation. In the capacity of depressor into cleaner procedures it is introduced thiourea in amount 0.5-3.0 kg/t, for depression of minerals-admixtures, fluorite or beryllium.
EFFECT: increasing of production data, reduction of content in concentrates admixtures, making difficult its following processing.
