The conditions for purification and waste-free utilization of the vanadate fraction of processing Ajinaur titanomagnetite concentrates in Azerbaijan by the carbonization method, including desiliconization, extraction of aluminum, regeneration of sodium carbonate and production of vanadium pentoxide, have been determined. It was found that TABAC (three alkylbenzylammonium chloride) is an effective extractant for extracting vanadium from carbonate – vanadate solutions without destroying carbonate ions. A technological scheme for processing carbonate-alkaline vanadate solutions to obtain vanadium pentoxide of reactive purity 99.7% corresponding in the quality to the analytical grade, g-Al₂O₃ and soda regeneration has been drawn up
