- Способ выделения европия из смеси РЗЭ заключается в восстановлении европия до двухвалентного состояния металлом-восстановителем (алюминия) и отделении концентрата европия в виде сульфата от сопутствующих РЗЭ. Восстановление проводят в присутствии фтор-ионов. Извлечение европия из суммы РЗЭ составляет до 98,5%, содержание его в конечном продукте - до 99,9%. Качество получаемого продукта регулируется заданием параметров процесса.
