Complex Loosening of Lepidolite Concentrate by Sulfuric Acid

Abstract

Experimental study of complex extraction of lithium and other valuable components from lithia mica – lepidolite was carried out. A method of complex processing of lepidolite is suggested in the present work, that provides extraction of such valuable components as lithium, potassium, cesium, rubidium, aluminum, and beryllium from this mineral. Moreover, energy consumption was minimal during this process. Results of the research set up preconditions for large-scale involvement of lepidolite in the hydrometallurgy of lithium, given the large number of proven deposits of lepidolite and the ever-growing demand for lithium products in different countries.
