Instead, uranium and other actinides are separated from the fission products by
Production techniques. Uranium ores differ widely in composition, containing a variety of other elements which must be removed. As a result the production methods differ considerably depending on the particular ore to be processed although in every case very selective processes must be used. The following is a common scheme.
ORE PROCESSING AND REFINING OF URANIUM IN INDIA. Uranium ores of commercial importance in India are of comparatively low grade containing less than % of uranium. A mill for processing the ore has been operating for over 10 years. A plant for refining the yellow cake and producing uranium metal of nuclear purity was set up in 1959.
· Plus new Safonov and Mikhailov deposits of uranium ores in the neighbouring Nikolaev region, where production of 150200 tons per year is supposed to be carried out by the method of borehole underground leaching.
