ABSTRACT:
Process for pelletizing sulphur by forming and solidifying molten droplets of sulphur containing dispersed therewithin an effective minor amount of a mechanical strength improving modifying additive, e.g. 4-10 ppm organopolysiloxane, kerosene, other lower boiling range straight chain hydrocarbon than kerosene, or mixtures thereof, for increasing the mechanical strength of the resultant pellets, such as by contact with water as coolant, either by feeding molten droplets of or an unbroken continuous stream of the molten sulphur-dispersed additive mixture into the water, preferably at a coolant temperature operatively below that of the molten sulphur and above its own freezing temperature and at a molten sulphur-dispersed additive mixture feeding temperature of particularly optionally between about 130.degree.-140.degree. C.; and
