Widely used in the mining industry as a flotation collector, especially for sulfide minerals such as copper, lead, and zinc. It enhances the separation of valuable ore from gangue by increasing the hydrophobicity of mineral surfaces, allowing them to attach to air bubbles in flotation cells. Effective at low concentrations and works well in alkaline conditions. Commonly applied in base metal and precious metal recovery operations. Also used in combination with other collectors to improve selectivity and efficiency. Its performance can be optimized by controlling pulp pH and dosage.
