Abstract

In the solvent extraction of uranium the three most commonly encountered operational problems are (1) the transfer of impurities on the loaded organic, (2) poor phase separation and (3) crud formation. The chemistry and physics associated with these problems are discussed and suggestions are made as to how circuit design and operating procedures can alleviate these challenges.
