Creation of theoretical basis for innovative technologies on physico-chemical studies of metalcontaining systems under conditions of hightemperature and hydrochemical processes

Project Manager: Abdulvaliev R.A.

Relevance: In this regard, fundamental studies of the kinetics and mechanism of interaction in multicomponent metal-containing systems are relevant and will become the physical and chemical foundations for the development of effective, environmentally friendly methods of flotation, high-temperature and hydrometallurgical schemes for processing low-quality mineral and technogenic raw materials with the extraction of non-ferrous, rare and noble metals. As a result of the program implementation, the theoretical foundations of a new class of microheterogeneous emulsion reagents will be created; theoretical data on phase transformations of complex mineral formations will be obtained; phase diagrams will be constructed and thermodynamic constants of formation and evaporation of alloys based on magnesium as a modifying or alloying additive are determined. The development of new technological solutions based on the results of theoretical studies will contribute to the introduction of innovations in the metallurgical and chemical industries, increase the production of non-ferrous, rare, rare earth and precious metals, resource conservation, and environmental problems. The results of the research will increase the industrial potential of the republic in the field of metallurgical production of noble, non-ferrous, rare, rare earth, and refractory metals through the use of innovative technologies. The program will explore: the flocculation flotation method to improve the recovery of fine minerals; the effect of bio-additives on the process of leaching precious metals from low-quality raw materials; the use of organic polyhydric alcohols for the sorption extraction of niobium, lithium, and REM; kinetic regularities of the process of decomposition of non-bauxite raw materials with the production of alumina and silicate sludge; distillation processing of magnesium alloys; interaction of titanium melts with zirconates and titanates; phase formation processes and the mechanism of formation of strong calcium phosphate coatings on titanium; Physico-chemical properties of oxide systems and forms of non-ferrous metal content in them.
