Abstract
Tri n-octyl phosphine oxide (TOPO) has been investigated as a refinery extractant for crude yellow cake prepared from El Atshan ore, Eastern Desert, Egypt. Relevant factors namely: type and concentration of acid, TOPO concentration, effect of temperature, residence time and organic/ aqueous ratio have been studied and optimized. The required number of extraction and stages was determined. Further purification could be achieved for the final product by selective precipitation of uranium peroxide from the stripped solution using hydrogen peroxide followed by its calcination. Complete chemical analysis of the final product has proved its nuclear purity. 8 figs., 3 tabs.
