    The Metallurgy of Cyanide Gold Leaching – An Introduction

     · Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

    SODIUM CYANIDE : Systemic Agent - CDC

    Sodium cyanide is water-reactive. Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas. Sodium cyanide solution in water is a strong base; it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.
