A simple process is described for producing hafnia-free zirconia by extraction with a solvent containing 60% vol tributyl phosphate and 40% mepasine. A twelve-stage mixersettler battery and a feed solution containing 80 g ZrO/sub 2/ /l were used. Feed and scrub solutions did not contain any additional salting out components such as sodium nitrate, and the solvent was not acidified separately before recycling. A possibility of reducing the number of stages in the extraction unit is observed. The use of very highly concentrated feed solutions does not seem to be advantageous. (auth)
