Extraction purification of scandium
- 1. Radievyj Inst., Leningrad (Russian Federation)
Description
The potentiality of a through extractional purification of scandium from small amounts of impurities (1%) using acid nitrate media and non-diluted tributylphosphate has been studied. Yb and Zr were considered as imitators of impurity element groups. The obtained isotherms of Sc extraction in case of initial acidity of HNO3 of approximately 8 mol/l and 11.5 mol/l in the presence of impurity elements, for which the distribution factors have been defined, are presented. On the basis of the data obtained a two-cascade extractional refining process has been formed and its process parameters have been calculated (and given for one of the cascades). 6 refs.; 3 figs.; 2 tabs
