Abstract

For the first time it is proposed to produce lithium hydroxide monohydrate as a primary derivative product from hydromineral raw materials. This technology is based on the primary lithium concentrate obtained by enriching the lithium-bearing brines and concentrating by the combined method. The produced concentrate is a pregnant lithium chloride solution which is subjected to the electrochemical conversion: LiCl ⋅ LiOH. The lithium hydroxide monohydrate crystals are extracted from the lithium hydroxide solution and, after washing, they correspond to the LGO-1 brand.
