  • OCCUPATIONAL HEALTH AND SAFETY IN URANIUM

    The uranium is transferred from the loaded solvent to an ammonium sulphate solution from which it is precipitated as ammonium diuranate by addition of ammonia. The diuranate is then dried and calcined (roasted in a furnace) to drive off the ammonia, leaving a uranium oxide product containing in Logistics of Uranium Mining Stanford University,2017-5-15 · The ore still must be subjected to the "uranium mill chemistry process" to become usable. The process is described in the following. Uranium Milling and the Associated Chemistry. The ore is first crushed and then mixed with water so it can move through the milling system in a more liquid form.
