Recovering Cyanide From Gold Plant Tailings

a processing plant, has probably been the single largest impediment to the implementation of cyanide recovery technology in the gold industry. In this regard, the mining industry can gain confidence and experience from the chemical industry, which manufactures sodium and calcium cyanide for the gold industry, and handles large quantities of

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.
