Continuous Precipitation of Uranium Peroxide at the Lodeve ...

Jan 01, 1987  INTRODUCTION The uranium ore processing plant at LODEVE applies an alkaline leaching process. The ore is leached in autoclaves by sodium carbonate at 140°C, and with an oxygen pressure of 600 kPa. This leaching provides liquors containing, in addition to the uranium, organic matter, zirconium and molybdenum.
