چکیده (انگلیسی):

The present work is concerned with selective separation of Y and Ce (IV) from the lanthanides cake prepared from the pregnant sulfate leach liquor of Abu Hamata sandy claystone ore material. This sulfate solution assays 0.32 g/L of Ln, 0.45 g/L of U together with 0.05 g/L V and 0.008 g/L B. It was used to prepare the lanthanides cake that contains 12.2% of Y and 37.4% of Ce. Ammonium carbonate solution in concentration of 200g/L was used for dissolving more than 95.1% of Y content selectively from the prepared lanthanides cake. The free Y lanthanides cake was then subjected to Ce (IV) separation via dissolving the other trivalent lanthanides in dilute hydrochloric acid while Ce(IV) remains insoluble.
