    Gold and silver are stripped from activated carbon on which they are adsorbed as cyanide complexes by subjecting the activated carbon to a stripping solution comprising as the strippant an effective amount of a compound containing the carboxylate functionality. The compound is preferably selected from benzoic and substituted benzoic acids and polyacrylic acids of less than about 100 000 m.w.

  • Extracting Gold HowStuffWorks

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically gold in the pulp dissolves. When workers introduce small carbon grains to the tank the gold adheres to the carbon.
