Study of an improved technique for precipitation of uranium from eluted solution

In the Uranium Corporation of India Limited, Jaduguda Mines in India, the yellow cake is precipitated from eluted solution as magnesium diuranate using magnesia. Because of the stringent specifications set by the Nuclear Fuel Complex, studies were implemented to produce uranium peroxide in place of magnesium diuranate. All the parameters such as precipitation pH, quantity of hydrogen peroxide required, duration of precipitation and temperature of precipitation were studied in detail and conditions for precipitation were optimised.
