    How gold is extracted by Cyanidation Process Refresh

    Jun 17 2020 Gold Extraction from Mines. Gold and silver are both extracted from the mines using the cyanidation process. This process is achieved by dissolving gold or silver in either a potassium cyanide or sodium cyanide solution. Mining companies also incorporate the use of a technical extraction process in the extraction of gold.

  • Extracting Gold HowStuffWorks

    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.
