APPARATUS FOR PRODUCING URANIUM CONCENTRATES FROM ACIDIC SOLUTIONS Russian patent published in 2017 - IPC C22B60/02 C22B3/44 

FIELD: metallurgy.

SUBSTANCE: invention relates to hydrometallurgy. Plant includes uranium regenerate collector, a stage of uranium concentrate precipitation reactors to obtain uranium concentrate precipitate, a collector with pipelines for dispensing neutralising reagent into uranium concentrate precipitation reactors, a filter press for dehydration of uranium concentrate precipitate, a vessel connected to stage of precipitation reactors for partial return of precipitate obtained in stage of precipitation reactors, and a mixer for uranium regenerate and precipitate, connected with uranium regenerate collector and with vessel for partial return of precipitate. Stage of precipitation reactors consists of at least two uranium concentrate precipitation arranged vertically one below other to move pulp from reactor to due to overflow, connected with a uranium regenerate and precipitate mixer and with filter press for dehydration of precipitate. Each of reactors is configured for bubbling pulp with air or inert gas through a perforated end of a pipe inserted through reactor and is collector pipeline for dispensing neutralising reagent.

EFFECT: higher content of uranium in concentrates due to higher degree of uranium extraction from solution, reduced impurities in concentrates.
