Product Overview

• Gel-type strong basic anion exchange resin (Type I, quaternary ammonium salt), specifically designed for gold extraction from gold cyanide leaching solutions. It exhibits high selectivity for gold-cyanide complexes (Au(CN)₂⁻) and is commonly used in RIP/RIL processes. CL-TTA is its high-capacity version with uniform particle size (525–625 μm).

• Key Performance and Application Selectivity: Au(CN)₂⁻ >> Zn(CN)₄²⁻ > Ni(CN)₄²⁻ >> Cu(CN)₃²⁻ (Higher selectivity for gold than copper, suitable for high-copper gold ores) Process Compatibility: RIP (resin slurry), RIL, column adsorption, no solid-liquid separation required for elution/regeneration: Low-temperature elution using thiourea/hydrochloric acid systems, high regeneration efficiency, long cycle life

• Typical Applications: Selective gold recovery from alkaline cyanide gold ore leaching solutions/slurries.

• Matrix Structure: Styrene-Divinylbenzene (Gel Type)
