Viklund, H I; Kennedy, R H

Uranium precipitates obtained from Congo leach liquors by an ion exchange process contained more than 0.1% chloride. Attempts were made to reduce the chloride content of typical precipitates by calcination of dried precipitate, releaching of dried precipitate with water, and washing of wet precipitate with water. Washing of wet precipitate with an aqueous solution of 0.25% Na/sub 2/SO/ sub 4/, to prevent peptization, provided a simple solution to the problem. Precipitation tests on Congo ion exchange eluates showed a marked advantage in subsequent thickening and filtration operations for precipitation from hot solution. (auth)
