Gold beneficiation reagents are functional additives used to extract gold from ores, primarily designed for different ore types such as gold and silver oxide ores, primary ores, and sulfide ores.
The core principle of gold beneficiation reagents is to disrupt the bond between gold and other elements in the ore through oxidation, complexation, or dissolution reactions, transforming it into a recyclable form. Taking environmentally friendly gold extraction reagents as an example, their components are typically a grayish-white powder mixture containing oxidants, complexing agents, and surfactants. The oxidant decomposes sulfides or organic matter in the ore, releasing the encapsulated gold particles; the complexing agent binds to gold ions, forming a stable, water-soluble complex that facilitates subsequent separation; and the surfactant reduces the surface tension of the liquid, accelerating the penetration and reaction efficiency of the reagent in the ore.
