FIELD: metallurgy.
SUBSTANCE: lithium extraction method includes batch preparation from the mixture of concentrates and flux, activating batch preparation and water leaching of activated batch. Additionally batch preparation is implemented from the mixture of lepidolite and spodumene concentrates per receiving mass ratio SiO2/(Na2O+K2O+Li2O) in mixture, equal to 4.5, and flux in the form of lithium carbonate per receiving of mass ratio SiO2/(Na2O+K2O+Li2O) in batch, equal to 2.3. Activating batch preparation is implemented by means of its melting at the temperature 1350°C, melt granulations by water, granulated melt crushing. Water leaching of activated batch is implemented while sulfuric acid presence.
EFFECT: receiving of relative clean by sodium lithium sulphate solutions, ability of lithium deep extraction from mentioned solutions into lithium carbonate.
