Specialty Resin
Alkaline Gold Cyanide Extraction Resin
This macroporous mixed amine anion exchange resin is specifically designed for the selective recovery of gold from high-copper cyanide slurries/leaches, exhibiting a significantly higher selectivity for gold than for copper.
Typical Applications
High-copper gold ore cyanide leaching solutions/slurries: Selectively adsorbs gold-cyanide complexes, separating impurities such as copper.
Precious metal recovery: Recovers gold, silver, and other metals from gold mines, silver mines, and non-ferrous metal smelting wastewater.
Resin-in-pulp (RIP): Directly processes the slurry, eliminating the need for solid-liquid separation and simplifying the process.
Key Advantages
High Selectivity
Au >> Zn > Ni >> Cu, enabling efficient gold extraction from high-copper slurries.
Easy Elution
Elution can be achieved at low temperatures with an alkaline mixture of sodium cyanide and sodium hydroxide, eliminating the need for thermal regeneration and the risk of releasing highly toxic hydrogen cyanide.
High Mechanical Strength
Large particle design, compatible with resin-in-pulp (RIP)/resin-in-leaching (RIL) processes, wear-resistant and shatter-resistant.
Strong Compatibility
Can be used independently or in conjunction with cyanide recovery processes such as SART.
