PLANT FOR PRODUCING URANIUM CONCENTRATES FROM ACID SOLUTIONS

摘要

Installation for producing uranium concentrates from acidic solutions after desorption of uranium from anion exchange resin and obtaining a commodity regenerate, including a collection of uranium commodity regenerate with a supply pipeline for uranium commodity regenerate, a cascade of deposition reactors for producing a precipitate of uranium concentrate, a collector with pipelines for the distribution of neutralizing reagents, a filter press, characterized in that it is additionally equipped with a local system of enrichment of commodity uranium commodity regenerate, connecting the supply pipe of uranium of commodity regenerate, a collection of uranium commodity regenerate with a cascade of deposition reactors to obtain a uranium concentrate precipitate and made in the form of a partial return tank for uranium concentrate sediment from a cascade reactor, a uranium commodity regenerate mixer and a uranium concentrate deposit from a partial tank for the partial recovery of uranium concentrate sediment connected by a supply pipeline from capacity for partial return of the sediment of uranium concentrate and the pipeline for supplying the mixture from the mixer to the reactors of the deposition cascade to obtain a precipitate of uranium concentrate, as well as an air or inert gas supply pipe, the end of which is perforated and introduced into each reactor of the deposition cascade to obtain a precipitate of uranium concentrate, while at least two precipitation reactors are located in the cascade of reactors located one lower in height associated with the collector and its piping distribution neutralizing reagents.
