Carbonate leaching of uranium

Creators

Description

The decomposition of hydrogen peroxide in aqueous ammonium carbonate leaching solutions of the type used in extracting uranium values from uranium-bearing ore zones is suppressed by maintaining such leaching solutions in contact with 1-hydroxethylidene-1, 1-diphosphonic acid and a tetrasodium pyrophosphate. The weight ratio of diphosphonic acid to total pyrophosphate can vary from about 1 to 10 to about 10 to 1, but is preferably about 1 to 6. (LL)
