Product Overview

• Ultra-high gold selectivity: Selectivity order Au > Zn > Ni >> Cu, with almost no copper adsorption, solving the problem of gold recovery from high-copper gold ores, and gold loading is not affected by copper.

• Excellent mechanical strength: Large particle size (800–1300 μm), wear-resistant, suitable for RIP (resin slurry) process, with low resin loss.

• Easy elution and recyclability: Gold loading can be eluted at low temperature with thiourea/hydrochloric acid, and the resin can be regenerated and reused, with a long cycle life.

• Application Scenarios Gold recovery from cyanide leaching solutions in gold ores: Selective adsorption of gold-cyanide complexes (Au (CN)₂⁻) from alkaline cyanide slurry/solution, especially suitable for complex gold ores with high copper, high zinc, and high nickel content. Process: Resin slurry process (RIP) or resin leaching process (RIL), directly adsorbing gold in the slurry without solid-liquid separation, simplifying the process and reducing costs.
