Bound up in consumer electronics, jewelry and the ores that it comes from, gold is difficult to extract, and most modern processes do it with a highly toxic combination of cyanide salts. The cyanide leaches the gold out, but the cyanide can seep into the ground, causing environmental problems and posing threats to human health.

Removing the cyanide from gold processing. Cyanide is used in the majority of gold processing operations simply because it is cheap and effective. "Others chemicals such as disulphide are not as effective and do not work on as many ores," says Mudd.

Environmentally friendly gold recovery - CSIRO

Replacing cyanide with the non-toxic thiosulphate will reduce the risks and environmental impacts of gold processing and may open up opportunities in areas where the use of cyanide is banned (including in several European countries and American states).

UTILIZING CYANIDE RECOVERY TECHNIQUES IN …

Cyanide in solution is combined with gold ore and leaches the metal to form a soluble cyanide gold complex. The gold is then typically adsorbed onto activated carbon for downstream recovery. The resulting barren solution, still containing cyanide but absent of gold, can then be recycled for reuse and leaching of new ore.

Gold Cyanidation - Ground Truth Trekking

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

The Chemistry of the Extraction of Gold

THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN);- and Cu(CN)!-. The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows: Au(CN); + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).

What is the role of cyanide in mining | MiningFacts.org

Role of cyanide in ore processing. Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. [3] The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889.

Gold mining - Wikipedia

The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
