  • Activated Carbon in Gold Cyanidation feeco

    The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.

  • Introduction to Cyanide Gold Mining

    Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold. Gold loaded onto the carbon is then stripped using either
