Abstract:

To develop the physico-chemical basis of a complex technology for processing slurries hydrometallurgical production of vanadium pentoxide it is necessary to know in what form vanadium compounds are in the dump sludge and at what stage of processing they were formed, which is why vanadium is not completely extracted into the solution. This paper investigates the behavior of vanadium in the existing process chain (with the study of intermediate products of technological conversion) using a set of modern analytical methods (X-ray diffraction, SEM, X-ray diffraction, thermogravimetry).

Keywords: vanadium, slag, sludge, vanadium pentoxide, oxidation state, phase composition, processing technology
