Rare and rare-earth elements in the metal-bearing coals of the north of the Lena Coal Basin

The increased metal-bearing capacity of coals from the Salga-Tabakh area in the north of the Lena Basin was established. In terms of the composition of rare-earth elements, they can be attributed to the collectors of the most expensive yttrium group. A process flowsheet was proposed for the extraction of rare-earth elements from coal ashes; this flowsheet can be used both independently and as a part of coal conversion processes with the production of liquid fuels and other valuable chemical products.
