Counterflow Leaching Technology for Vanadium from Vanadium Pentoxide Hydrometallurgical Production Slurry

Research is conducted for creating technology for processing hydrometallurgical production of vanadium pentoxide slurries. The technology includes threestage counterflow leaching of vanadium from slurries and hydrolysis of a vanadiumcontaining solution. The V2O5 content is ≈ 70 wt.% in the resultant concentrate,
