The purpose of the work: establishing patterns, improvement of methods, tools and technologies for efficient and safe production and processing of uranium and zirconium ores and rational management of radioactive waste. The possibility of resource conservation with the chlorine technology of zircon processing alkalis, which provides high quality of products; Mathematical models of ionizing radiation in protective containers were developed, which for the first time take into account the geometry of the container, the intensity of radiation sources and the duration of the exposition; a mathematical model of turbulent dust transfer of dust particles has been developed; An expression was obtained to determine the concentration of the smallest dust particles in the turbulent stream, taking into account its coagulation; the patterns of changes in the performance of vibration feeders are established; the degree of radiation impact of the environment on the physical and mechanical characteristics of rubber elements is established; the patterns of changes in the efficiency of operation of cleansing devices of mine trolleys are established; The patterns of changes in the performance of drum mills, depending on the structural features of rubber fuerrows, are established; the determined uranium distribution factor for granular ion exchange resins, fibrous sorbents and materials based on vegetable raw materials; clarifying the dependence of the velocity of the separation of the material particle from the surface of the vibration, taking into ac Product Description popup.authors Ishchenko Kostiantyn S.
