<p>In a process for solidifying molten sulphur by pelletizing, pastillating or slating, the hardness of the end product is improved by heating the molten sulphur to a temperature greater than 160.degree.C, preferably 180-200.degree.C, before commencing the solidification process. The main solidification process described is pelletizing, and this is preferably performed by cooling the previously heated sulphur to 145-155.degree.C before introducing it as a molten stream into an aqueous coolant and incorporating a silicon compound as an additive in the molten sulphur to further improve product hardness.</p> |
