    4.4.1. Free Cyanide Recovery by RIP Using Zinc Precomplexation. Zinc cyanide is found naturally in many gold leach circuits, particularly those employing the MerrillCrowe process for final gold recovery. In addition, a zinc salt can be added to the leach tailings to precomplex all of the free cyanide as the zinc cyanide WAD complex.

  • 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.

  • Cyanide Leaching Mining SGS

    Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
