Toxic sodium cyanide has been used in gold mining since 1887, and it remains the primary reagent in use for gold processing today because it allows for efficient extraction of gold from low-grade ore.
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.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Cyanide use in mining Gold typically occurs at very low concentrations in ores – less than 10 g/ton. The most used process for gold extraction is hydrometallurgical recovery (gold cyanidation), which involves a "leaching" step during which the gold is dissolved in an aqueous medium, followed by the separation of the gold bearing solution from the residues. Gold is one of the noble metals
So cyanide is a leaching agent in this gold mining process the gold cyanide mining method mainly includes the following two steps 1 cyanide leaching in a thin cyanide solution in the presence of oxygen or oxidant the gold in the gold ore reacts with cyanide to form a monovalent gold complex which dissolves into the solution to give a leachate.

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
