Zone-refining, the purification of a metallic ingot resulting from the passing over its length of a comparatively short molten zone, has been found useful in the purification of several metallic elements. The impurities present in an elemental metal are often more soluble in the molten zone than in the solid material, and are carried to one end of the bar in the molten zone. This molten-zone movement can be repeated any number of times on a metallic ingot, with the zone always being moved in the same direction.
