    The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation. The eluted and regenerated carbon is screened at about

  3. Carbon Regeneration - Mineral Processing & Metallurgy

    In normal process streams activated carbon is exposed to a variety of chemicals. Organic compounds tend to adsorb readily on the hydrophobic activated carbon, which reduces site availability for gold cyanide. Other compounds such as calcium and magnesium carbonate commonly precipitate on the carbon surface and restrict gold adsorption access.
