FIELD: metallurgy.
SUBSTANCE: invention refers to method of processing spodumene concentrates. The purpose of the suggested invention is development of such method of processing spodumene concentrate. The method consists in activation of the concentrate by means of melting with lithium carbonate taken on consideration of obtaining weight ratio SiO2/(Li2O+Na2O) in charge equal to 2.7-3.0. After activation there is performed sulphuric acid leaching of activated material.
EFFECT: production of sodium pure solutions of lithium sulphate further allowing deep extraction of lithium out of said solutions into lithium carbonate.
