Extraction of Vanadium from the Dust of Ore-Thermal Melting ?f Ilmenite Concentrate Using Deep Eutectic Solvents

During the production of titanium slag by melting ilmenite concentrate, a large amount of dust is formed, most of which is taken to the landfill. The problem of dust disposal and recycling is the most important task of titanium production, since valuable components that can be extracted are lost alo...
