Abstract
1,223,682. Separation of Thorium, Cerium, Ytterbium and Yttrium. W. J. REYNOLDS HOLDINGS Ltd. 15 Feb., 1968 [23 Feb., 1967], No. 8795/67. Heading C1A. The separation of Th from Ce<SP>IV</SP> or Yb<SP>III</SP> from Y is effected by the preparation of their alkali metal double carbonates and crystallization thereof in alkali metal carbonate solution. To separate Thorium it is preferable that the starting material contains water-soluble Th compounds and light rare earths (i.e. elements with atomic nos. 57-63 inclusive) and only a minor proportion of Y. This can be achieved by the method as in Specification 1,223,683. Any Cerium present is oxidized to the Ce<SP>IV</SP> state. The water-solubles from the process are converted to carbonates and the soluble carbonates dissolved in alkali metal carbonate solution, insoluble carbonates removed and solution treated to reduce Ce<SP>IV</SP> to Ce<SP>III</SP> which is removed. Thorium alkali metal double carbonate is crystallized out. Cerium is separated by oxidizing the pptd Ce<SP>III</SP> carbonate and then forming double carbonate as with Th. Yttrium is separated from materials containing water-soluble Y compounds, preferably with very low Yb content so that reduction to Yb<SP>II</SP> is unnecessary. The alkali metal carbonate solution is used at concas, greater than 10%. The double carbonate may be converted to oxalate or nitrate and then to the oxide.
