Abstract
A method for processing lanthanum oxide solids in an aqueous solution. An aqueous solution containing a partially soluble or insoluble salt forming anion is provided. A soluble lanthanum oxide solid is then added to the solution, and the anion is then reacted with at least a portion of the lanthanum in the lanthanum oxide solid, thereby forming a partially soluble or insoluble salt coating around the lanthanum oxide solid.
