  • How Cyanide Leaching is Used in Gold Mining

    Of those methods, the Cyanide Leaching Process (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium cyanide solution. This article will give a general overview about how this important, 120 year old gold mining process works.

  • Gold Cyanidation Process Mineral Processing Metallurgy

    The Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated.

  • Cyanide Leaching Of Gold Mine Engineer.Com

    Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the MerrillCrowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon.
