Gold Extraction Ion Exchange ResinAnion exchange resin uses ions with negative charges. They are divided into strong base or weak base anion exchange resins. Weak acid anion exchange resin is used for the extraction of gold, which forms a negatively charged complex with cyanide in alkaline solution. ([Au(CN)_2]^−)
Advantages of Ion Exchange Resin in Gold Extraction:
Selective Adsorption: High selectivity for gold over other metals.
Regeneration: Resins can be regenerated and reused, reducing operational costs.
Environmental Benefits: Reduced use of toxic chemicals compared to traditional methods.
Applications
Anion Ion Exchange Resin are widely used in the gold mining industry, particularly for processing low-grade ores and for refining gold from recycled electronics and other materials.
