Zinc sulfide pellets were reacted with steam to obtain elemental sulfur and zinc oxide. Addition of an appropriate amount of oxygen to steam was found effective for the purpose. Addition of neither hydrogen to steam nor carbon to zinc sulfide was effective. It has been suggested that zinc oxide formed on the surfaces of zinc sulfide pellets promotes the Claus reaction to form elemental sulfur.
