cyanide process | Infoplease

The precipitate is further refined, e.g., by smelting to remove the zinc and by treating with nitric acid to dissolve the silver. The cyanide was developed 1887 by J. S. MacArthur and others in Glasgow, Scotland. It is now the most important and widely for from ores.

  • 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.
