Abstract

Phosphorus impurities are removed from yellowcake by dissolving it in hydrochloric or sulfuric acid to a U3 O8 assay of at least 150 g/l at a pH of 2; precipitating uranium peroxide with hydrogen peroxide while keeping the pH between 2.2 and 2.6 and recovering the uranium peroxide from the phosphorus impurities remaining in solution.
