ABSTRACT:
Impurities are removed from pieces of sulfur by dropping the pieces directly into a bath of heated liquid sulfur disposed in a vessel. The liquid sulfur is heated externally of the vessel and conveyed thereto. The sulfur pieces melt in the bath. A movable element, such as a rotary screen drum or conveyor blades for example, is disposed in the bath for agitating the bath and entraining the impurities.
