Problems solved by technology

[0004] Using the saturated re-adsorption process, more than half of the eluting qualified liquid needs to be returned for re-adsorption, and the saturated re-adsorption tail liquid produced needs to be recovered and adsorbed, and the process is relatively complicated; between the adsorption tower and the transition tower, a saturated re-adsorption tower and a recovery adsorption tower are required , 3-tower series countercurrent leaching and corresponding resin lifting tank and other equipment, the equipment occupies a large area and investment, and the operation and control are not easy
[0005] The leaching process is to connect the extraction and stripping process after the saturated resin leaching, and then enrich and purify the uranium in the enrichment solution. If the raffinate water phase is not completely removed from the organic phase, resin poisoning may occur if the raffinate water phase is mixed into the ion exchange system. At the same time, organic extractants are flammable and non-environmentally friendly reagents, and there are certain safety and environmental protection pressures in their storage and operation.

Abstract

A U-shaped structure uranium washing device, including a U-shaped structure tower body and a resin storage tank, at the left end of the U-shaped structure tower body, there is a lean resin outlet and a leaching agent inlet; the upper right end of the U-shaped structure tower body is connected to the resin storage tank, The resin storage tank has a compressed air inlet, a primary saturated resin inlet, an overflow port, and a tail liquid outlet on the right end of the U-shaped structure.

Description

technical field [0001] The technology belongs to the technical field of in-situ leaching of uranium ore, and in particular relates to a technology and system for leaching primary saturated resin produced by acid in-situ leaching leachate adsorption, and relates to a U-shaped structure for efficient leaching of acid-in-situ leaching leaching solution adsorption The technology and system of the produced primary saturated resin relate to a U-shaped rinsing tower device. Background technique [0002] Domestic acid in-situ leaching uranium mines mainly use sulfuric acid as the leaching agent, and uranium mainly exists in the form of uranyl sulfate in the acid leaching solution. In-situ leaching mines and hydrometallurgical plants generally use an ion exchange system to recover uranium in the leaching solution. Due to the low uranium concentration in the acid in-situ leaching leaching solution, the ratio of sulfate ion concentration to uranyl ion concentration is high, and the com...
