With the depletion of high-grade gold ore, modern gold mining faces challenges of low-concentration ore treatment and cost control. Activated carbon has become a core adsorbent for commercial gold hydrometallurgy. It replaces traditional zinc precipitation processes due to its high porosity, stable physical and chemical properties, and selective adsorption capacity, supporting efficient and economical large-scale gold recovery worldwide.

Treatable Substances

• Gold cyanide complexes: Selectively adsorb dilute gold-cyanide anions from leachate and ore pulp, the primary target for gold enrichment.
• Impurity metal complexes: Adsorb interfering copper, nickel and silver cyanide complexes to purify gold leachate and reduce impurity interference.
• Organic impurities: Remove residual organic pollutants in ore pulp to avoid preg-robbing and improve adsorption efficiency.
