The negative impact of vanadium-containing technogenic waste in the form of tailings from titanomagnetite ore deposits and metallurgical production slags on the environmental situation in industrial regions and the need for their disposal is shown. This will not only expand the raw material base of vanadium, but also save primary mineral vanadium-containing resources. The importance of vanadium in various industrial sectors is assessed and the prospects for its consumption in the world are considered. It is relevant to obtain it from technogenic materials due to the growing demand for vanadium on the market. The hydrometallurgical extraction of vanadium from technogenic raw materials is considered using methods of acid and water leaching of technogenic vanadium-containing materials of various origins and chemical compositions, oxidative roasting of materials at different temperatures, and the use of various additives to increase the degree of vanadium oxidation during roasting. The vanadium content in the resulting solutions and solid samples was determined by X-ray fluorescence spectroscopy (XRF). Analysis of the experimental results showed that processing modes for man-made materials must be selected taking into account their chemical composition. The most effective reagents for firing this type of vanadium raw material are NaCl and Na2CO3 additives; the recommended firing temperature of the charge with reagents is 950 °C, followed by water or acid leaching. At the same time, the highest degrees of vanadium extraction were 74.8–91.9 %.
