Specialists of the Institute of Chemistry and Technology of Rare Elements and Mineral Raw Materials have improved the sulfuric acid technology, which ups the extraction rate of lithium from pegmatites to about 90%.
According to RIA Novosti, experts have improved the existing method. The improvement will allow to extract 98% of the metal. The end products are lithium carbonate or lithium hydroxide.
The report clarifies that the institute synthesized solid electrolytes with the NASICON structure from lithium carbonate. This product is considered optimal for use in the manufacture of solid-state lithium-ion batteries.
The application of sulfuric acid technology requires large volumes of sulfuric acid. The Kola Mining and Metallurgical Company, part of Norilsk Nickel, can become a supplier of raw materials.
