Abstract
Lithium production in Kazakhstan could be strategically important for the country as there has been a growing demand for this metal for the production of lithium-ion batteries, which are widely used in electric vehicles, portable devices and for storing energy from renewable sources. In addition, Kazakhstan is actively developing its lithium industry and is looking for ways to make the most efficient use of its lithium resources to support global energy. The use of highly selective sorbents can play a decisive role in the development of lithium-containing natural resources. The paper presents the results of research on acid treatment. X-ray phase analysis showed that the obtained manganese dioxide sorbent has a cubic crystal lattice structure.
