A method of recovering contaminating or valuable components from a solid feed material (10), includes feeding the material (10) into an optional grinder as a pretreatment (12), then into a heated melter (14) along with a material (16) that provides fluorine, to provide a molten or semi-molten material, where the molten material is then reacted with water or an acid solution (22) in vessel (20), to form a dissolved molten or semi-molten salt in solution, which can be passed to extractor (26) or the like and provide a concentrated stream of the valuable or contaminating components (30).
