A blended surfactant-based leaching aid designed for copper ores. It significantly reduces the solid–liquid interfacial tension, enhances the penetration of leaching solution into ore cracks and pores, and accelerates copper ion migration to the liquid phase, resulting in higher copper leaching rates. Highly acid-resistant and compatible with sulfuric acid leach systems, it offers simple operation, is safe to handle, and poses no interference to downstream extraction.
