There is disclosed a novel method for enhancing the flow of particulate material, particularly carbide-based desulfurizing agents (DSR's) used for the removal of sulfur from hot metal. A novel composition is also taught in which the DSR is in admixture with an organic polar liquid flow promoter. The novel composition has improved flow characteristics or flowability and reduces the possibility of clogging in conduits and lances.
