Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.

Melting is the process of changing a solid to a liquid using heat. Once this process is completed, the melted material cools and becomes a solid once again. Smelting, on the other hand, involves changing the chemical content of the material. When you smelt, you are "burning off" the other materials that your gold is currently mixed with ...

With ores of higher gold content ( i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.
