ABSTRACT A process and apparatus are described which control and inhibit the generation of sulphur dust. Dry solidified sul- phur in the form of chunks, powder, flakes or slates is sprayed or wetted down with liquid sulphur. Sulphur dust that is generated and becomes air-borne is sucked off, and either returned to the dry system, or is melted, and then sprayed as liquid sulphur to "wet down" the dry solidified sulphur. Contamination of the sulphur by other substances is mini- mixed; as is the loss of air-borne particles of sulphur into the atmosphere. Spraying of liquid sulphur is done at "transfer points" where dry solid pieces of sulphur are being handled, moved, conveyed or dumped from one location to another. Sulphur in liquid form sprayed onto the surface of dry pieces carried in open railway hopper cars is used, for example, to seal the surface against wind erosion. In a broad sense, the process can be applied to dry- solidified dust generating material that is capable of being liquified.
