Abstract:

We present results of geological-mineralogical-geochemical studies of the Tebinbulak scandium-containing titanium-magnetite deposit in Western Uzbekistan. The levels of scandium content in ores and rocks of the pyroxene-hornblende massif have been analyzed. The potential for the associated extraction of scandium from ores, which can significantly increase the profitability of the industrial development of the deposit, is discussed.

Abstract:

In the northern Fennoscandian Shield, vanadium mineralization occurs in the Paleoproterozoic Pechenga–Imandra-Varzuga (PIV) riftogenic structure. It is localized in sulfide ores hosted by sheared basic and ultrabasic metavolcanics in the Pyrrhotite Ravine and Bragino areas and was formed at the latest stages of the Lapland–Kola orogeny 1.90–1.86 Ga ago. An additional formation of vanadium minerals was derived from contact metamorphism and metasomatism produced by the Devonian Khibiny alkaline massif in the Pyrrhotite Ravine area. Vanadium forms its own rare minerals (karelianite, coulsonite, k

Abstract:

Abstract Scandium is often associated with iron oxides in the environment. Despite the use of scandium as a geochemical tracer and the existence of world-class supergene deposits, uncertainties on speciation obscure the processes governing its sequestration and concentration. Here, we use first-principles approaches to interpret experimental K-edge X-ray absorption near-edge structure spectra of scandium either incorporated in or adsorbed on goethite and hematite, at concentrations relevant for the environment. This modeling helps to interpret the characteristic spectral features, providing ke

Abstract:

The study covers scandium adsorption in batch conditions by VSK, DAS and PFT activated carbon grades (Russia) of different origin (сoconut shell, аnthracite, thermoset waste, respectively) from sulfuric acid-chloride solutions (pH = 2) simulating the composition of the underground leaching solutions of polymetallic ores. It was found that scandium adsorption by DAS and VSK carbons proceeds with the highest distribution coefficients (133 and 45.8 cm3/g, respectively). Isotherms of scandium adsorption with these carbons are linear and described by the Henry equation with constants 133 ± 21 and 4

Abstract:

A group of metals, including tantalum, rare earth metals, beryllium, titanium, zirconium, rhenium, scandium and boron has a big importance for alloying steel, aluminum and other non-ferrous metals as well as for production of different alloys. In Russia, the explored resources of tantalum by many times exceed the plants’ demands. Zashikhinskoe and Vishnyakovskoe deposits in Irkutskregion, as well as Katuginskoe in Chitaregion are most promising. The State balance accounts the resources of rare earth metals (REM) oxides by 20 deposits. Russiatakes the second place in the world after Chinaby REM

Abstract:

This paper presents the results of a study of experiments on the sorption characteristics of phosphorus-containing ion exchangers Purolite MTS9580 (functional group ‒ derivatives of phosphonic acid) and Lewatit TP260 (functional group ‒ aminomethylphosphonic acid) on scandium. Using the method of low-temperature nitrogen adsorption, structural characteristics of selected ion exchangers Purolite MTS9580 and Lewatit TP260 respectively were measured. The specific surface of Purolite MTS9580 and Lewatit TP260 ion exchangers was measured as 5.1 and 4.5 m2/g, respectively. The obtained values indica
