For separating sulfur from a sulfur-lye suspension, the suspension is fed into a flooded separation tank, a temperature above the melting temperature of sulfur is maintained in the separation tank, and liquid sulfur and lye are withdrawn from the separation tank. To reduce the formation of sodium thiosulfate, the area of the interfacial separation layer between liquid sulfur and lye is maintained as small as possible in separation tank (15) by providing that the liquid sulfur be fed into a relatively small diameter vertical separation pipe (4), in which the separation layer (6) between liquid sulfur and lye is established, and the liquid sulfur is drained out through separation pipe (4).
