Abstract

The studies on vanadium production are generalized, and the promising nature of flotation is demonstrated in this regard. The prognostic selection of fulvic acid FulvAc as a selective collecting agent relative to vanadium occurred as vanadyl VO \(^{2 +}\)  in acidic pregnant solutions is justified. The analysis of chemical reactivity studied the mechanism of vanadyl extraction and concentration using chelating agent FulvAc. Computer modeling is performed for a flotation system representing a slightly soluble metal complex of vanadyl fulvat [VO \(^{2 +}\) –FulvAc] \(_{n}\) . Efficiency of FulvAc is proved by lab-scale flotation tests with recovery of vanadyl not less than 92%. Vanadium oxisols are demandable by different industries, and [VO \(^{2 + }\) –FulvAc] \(_{n}\)  is usable as complex mineral supplements for fertilizing mixtures for urban greening.
