Cationic Collector Complex (Quaternary Ammonium Type)
Quaternary ammonium cationic surfactant complexes are used as collectors in reverse flotation circuits for silica removal from iron ore and phosphate concentrates, and in potash ore processing. Unlike primary amines, these quaternary compounds remain fully ionized across the entire pH range, providing consistent collector performance regardless of pulp pH. They offer strong adsorption on negatively charged silicate mineral surfaces via electrostatic interaction.
