OraPure Activated Carbon for Gold Recovery

OraPure is intended for industrial gold mining environments where operating conditions are demanding and logistical support may be limited. Its material properties support stable performance in gold cyanidation circuits, including applications where consistent recovery efficiency and long service life are critical.

In cyanide gold extraction processes, gold is dissolved as stable gold cyanide complexes. Gold recovery using activated carbon occurs when these complexes are transported into the internal pore structure of the carbon and adsorbed onto the internal surface.

OraPure Activated Carbon is manufactured with a hierarchical pore structure consisting of macropores, mesopores, and micropores.

• Macropores act as transport pathways for gold bearing solutions.
• Mesopores support diffusion and intermediate adsorption of gold complexes.
• Micropores provide the primary adsorption sites where gold retrieval occurs.

This pore architecture enables efficient mass transfer and stable gold adsorption under continuous flow conditions, supporting predictable gold recovery performance in industrial mining circuits.

Controlled ash content and a low impurity profile minimize interference with gold adsorption and reduce the risk of fouling during elution. This contributes to consistent gold recovery efficiency over extended operating campaigns, particularly in remote gold mining operations where process stability is essential.

• Carbon‑in‑Pulp (CIP) gold recovery systems
• Carbon‑in‑Leach (CIL) gold extraction circuits
• Carbon‑in‑Column (CIC) gold adsorption operations
• Heap leach gold recovery systems

Its mechanical strength and adsorption characteristics allow reliable performance in both agitated tank systems and colum based gold recovery processes.
