FIELD: processing lepidolite concentrates. SUBSTANCE: proposed method includes preparation of charge containing lepidolite concentrate and alkali flux, melting this charge with alkali flux, water granulation of melt for obtaining granules, grinding these granules and performing sulfuring acid leaching. Used as alkali flux is sodium carbonate satisfying required relationship of silicon and sum of sodium, potassium and lithium in terms of oxides equal to 2.89-3.45. EFFECT: reduction of consumption of alkali flux and sulfuring acid; reduced power requirements. 2 tbl
