Application

  • Gold Mine Hydrometallurgy

    This combination is widely used in heap leaching, CIP and CIL gold extraction processes. Sodium cyanide dissolves gold from ores through complexation reaction. Sodium hydroxide adjusts the pH value of ore slurry to prevent harmful gas volatilization and stabilize leaching environment. Activated carbon effectively adsorbs gold complexes to improve gold recovery rate, matching various gold ore production lines.

  • Precious Metal Electroplating

    The three chemicals form a matched system for silver and gold electroplating. Sodium cyanide acts as complexing agent to obtain smooth and firm plating layers. Sodium hydroxide balances bath alkalinity and removes impurity ions. Activated carbon filters organic contaminants in plating solution to extend service life of electroplating liquid.
