URANIUM RECOVERY BY CONTINUOUS ION EXCHANGE OF

In uranium ion exchange, strong base anion resins are normally used. The strong base anionic The continuous Ion Exchange (CIX) process utilises a larger number of smaller ion exchange columns (frequently more than 20 columns) which operates in a continuous manner via counter- current contacting of liquid with resin.

Uranium Mining Overview World Nuclear Association

Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ====> UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-====> UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali, e.g. as sodium

Uranium DuPont

Groundwater Remediation . Uranium is a natural element found in groundwater throughout the world and regulated in some countries. Uranium is usually present as the monovalent uranyl ionic complex (U 3 O 8-) at very low levels in groundwater and thus the most cost effective treatment is to remove the uranium with a highly selective ion exchange resin and then dispose of the uranium-loaded resin.

Uranium processing Uranium processing Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore
