Abstract	Complex research of technogenic raw material samples is carried out. Using the methods of X-ray diffraction and X-ray fluorescence analysis, the chemical and phase compositions of roasted vanadium slag and slime are established. The compounds of the base elements are extracted sequentially according to a three-stage scheme recommended by the European Commission. Their low mobility is recorded. Vanadium and manganese compounds possess higher mobility in the slag than in the slime. Iron and chromium form solid oxides and silicates that are disintegrated only under the action of HNO$_{3}$. The methods of microwave plasma atomic emission spectrometry (MP-AES) and inductively coupled plasma mass spectrometry (ICP-MS) are used to determine the gross contents of V, Mn, Fe, Cr, Zn, Ni, Ba, Sr, Rb, Y, Ga, Ge, Mo, La, and Ce in the samples of slag and slime. It is shown that the total concentration of V, Mn, and Cr considerably exceeds the values of the maximum allowable concentrations (MAC) of these elements established for soils, objects with a sample base that is no less complex. Possible leaching of the forms of elements from solid samples of vanadium slime and slag with 0.1 M Na$_{2}$CO$_{3}$ solution and the mobile phase for reversed-phase high performance liquid chromatography (RP HPLC) is studied. Mostly, vanadium compounds are extracted under these conditions. Manganese compounds are extracted by 1–10%. An inconsistency is found between the time of retention during the chromatographic separation of V and Fe forms in the model mixtures and solutions obtained after the samples of vanadium slag and slime have been chemically treated.
