“…While the nickel's deposited coating was examined by X-ray phase analysis (table 2), scanning electron microscopy (fig. 3) and energy dispersive X-ray spectroscopy (table 3), which were used to analyze the structure, as well as the elemental and morphological composition of the coating [32]. Nickel and copper contents were about 20 % and 80 % sequentially (table 2).…”

Earlier, the authors had already successfully proposed a method for extracting minerals from crude oil as a first step, to be further developed in this second step in the direction of obtaining solid (metallic and / or oxide) phases of nickel and vanadium. The scientific, practical and strategic importance of the work is clearly-underlined with a general depletion of vanadium and nickel ores. In the current situation of mineral resources with a general depletion of vanadium and nickel ores, it becomes necessary to search for new and alternative resources to obtain these strategic and important metals and their compounds from available resources. Taking into account that vanadium and nickel ores are practically absent in the raw material resources base of some countries, such as Middle East's countries. Thus, a high percentage of imports of this metal product remains, which worsens the economic situation that has developed during political conflicts. The scientific approach was based on a combination of hydrometallurgical and electrometallurgical experiments, consistently carried out through the processes of sorption and desorption during cathodic electrodeposition. Sorption processes for vanadium and nickel were carried out using a mixture of Syrian sorbing materials (incense-type resins and surface-activated natural clays) with finely ground glass SiO 2 . Cathodic electrodeposition experiments were carried out on a copper cathode plate, and on the other hand, an insoluble glassy carbon electrode was used as the anode. All batch experiments were carried out to determine the best conditions for vanadium and nickel sorption by studying six different parameters affecting the sorption capacity of vanadium and nickel. As a result, the maximum sorption capacity of vanadium and nickel was 87.5 % and 91.3 % consistently under the predetermined conditions. Eventually, 7.6 % Ni (with a purity of 97 %) was recovered from the solution after the desorption process by the electrolytic method (during electrolysis); 15.6 % (99.3 % pure) V 2 O 5 and 11.5 % (79 % pure) NiO chemically.

This paper is aimed at developing an integrated criterion used to evaluate not only the quality of materials, but also the effect of the material preparation method on the activity of the particles. We studied cryptocrystalline graphite in natural and mechanically activated states from the Kureisckoe deposit. Graphite was activated in a planetary centrifugal mill at Mamina Laboratory of Disperse and Nanostructured, Solid, Viscous and Colloid Materials of Siberian Federal University. In the course of the studies, the authors proposed an empirical criterion based on differential scanning calorimetry to evaluate the energy saturation of filling components for non-stick coatings based on activated cryptocrystalline graphite -the conditional activation criterion. The calculated dependence of this criterion on the activation time proved data earlier obtained: the most optimum graphite activation time in the planetary centrifugal mill is 20 minutes.
