Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
Gold is very unreactive and is found as a native metal in the free state. So, it does not need to be chemically separated. Thus, gold is leached to get pure metal. During leaching process, gold (Au) is first oxidized by oxygen of the air to Au + cation which then combines with CN-ions to form the soluble complex, sodium dicyanoaurate(I).
Gold concentration may occur as other minerals are leached away over a long period. Ore of sufficient yield is very rare. Gold's Extraction and Purification# Because of gold's inertness some 80% of gold within ore is in its elemental state. There are several processes for extracting, and then purifying it.
Cyanidation is a method used in the extraction of gold from its ore. This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores.
