Used primarily in the mining industry as a flotation agent for the separation of ores, particularly copper, nickel, and zinc. It enhances the hydrophobicity of metal sulfide particles, allowing them to attach to air bubbles and rise to the surface for collection. Also employed in the rubber industry as a vulcanization accelerator, improving the elasticity and durability of rubber products. Additionally, it finds application in organic synthesis as a reagent for introducing xanthate groups into molecules, aiding in the production of various chemical intermediates.
