Used primarily in the mining industry as a flotation collector agent to separate sulfide ores from gangue minerals. It selectively binds to metal sulfide surfaces, making them hydrophobic so they can attach to air bubbles and be separated from the ore slurry. Effective in the extraction of copper, nickel, lead, and zinc. Also used in the production of rubber chemicals and as a intermediate in organic synthesis. Its performance is pH-dependent, typically used in alkaline conditions to maintain stability and activity.
