Gold Extraction Resin
CH197 is a high-selectivity chelating ion exchange resin with quaternary ammonium functional groups, engineered on a durable styrene–divinylbenzene network matrix for efficient gold extraction and metal recovery.
Introduction
Comcess chelating resin is an ion exchange resin with functional groups with strong affinity forchelating alloyson styrene-divinylbenzene copolymer. Comcess®CH197 resin has high selectivity and high exchange capacity for gold due to its special functional groups, and has excellent wearresistance and penetration resistance due to its network structure. It is easyto elute after adsorption saturation and can be used continuously in a cycle.
