Technological mineralogy: development of a comprehensive assessment of titanium ores (exemplified by the Pizhemskoye deposit)

Technological mineralogy of titanium ores is the basis for assessing their complexity. It enables, from a unified standpoint, to trace entire course changes in mineral matter through operating procedures, including beneficiation, processing, and obtaining target industrial products. The study targets are Pizhemskoye ilmenite-leucoxene sandstones, which distinguished by complex polymineral composition. Along with main ore components, there other metals different speciation (isomorphic admixture, independent phases). optimal set mineralogical analysis methods predictive assessment further use substantiated exemplified deposit, complex, noted variable content iron oxides contain rare earth metals. Examinations X-ray phase scanning electron microscopy confirm that phases sandstones pseudorutile aggregate, “leucoxene”. Considering granulometric peculiarities magnetic non-magnetic fractions gravity concentrate, prospects technologies processing raw materials discussed. problems high-quality materials, transformations as result extreme impacts physicochemical properties consequence isomorphic substitution part Ti atoms natural modifier agents (Fe V) synthesis oxide nanostructures applications considered (photocatalytic nanoreactor).
