method of preparing uranium concentrates by deposition of псевдоожиженного layer and preparing uo3 and U3O8 by drying / tube named concentrates

摘要

method of producing uranium concentrate in the form of solid particles by deposition from solution using u0443u0440u0430u043du0441u043eu0434u0435u0440u0436u0430u0449u0435u0433u043e u043eu0441u0430u0436u0434u0430u044eu0449u0435u0433u043e agent in vertically the reactor (1), mcomprising the base (7), the top of the central part (2), the upper part (3) and the lower part (6).and the hard particles of uranium concentrate form u043fu0441u0435u0432u0434u043eu043eu0436u0438u0436u0435u043du043du044bu0439 layer under the action of the rising liquid flow, which circulates from the base (7) to be u0440u0445u0443 reactor (1).sequentially passing through the lower part (6), a central part (2) and the upper part (3) of the reactor (1).and that is created by the flow of liquid u0440u0435u0446u0438u0440u043au0443u043bu044fu0446u0438u043eu043du043du043eu0433u043e input (11) in the base (7) of the reactor (1).and the liquid u0440u0435u0446u0438u0440u043au0443u043bu044fu0446u0438u043eu043du043du044bu0439 flow recombine at the first predetermined specific level (a) in the upper part (3) of the reactor and sent back to dos without evaporation u043eu0432u0430u043du0438u044e (7) of the reactor (1).after which the excess fluid going through the top discharge (10).located at a second predetermined level (in) in the upper part of the reactor; and (3) the upper level (c) u043fu0441u0435u0432u0434u043eu043eu0436u0438u0436u0435u043du043du043eu0433u043e layer solid particles, so they wayhe was at a level below the first and second predetermined certain levels.
