Cyanide recovery can have a significant impact on the economics of processing high cyanideconsuming coppergold orebodies. When cyanide destruction is practised in these situations, the operating costs associated with cyanide alone will amount to more than US2/kg of cyanide .

What is Gold Cyanidation? (with picture)

Gold cyanidation extracts gold from the ground. Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

the production of gold are based on the use of cyanide (Hilson, 2006). In this method a weak sodium cyanide solution (NaCN) of 100500 ppm is used. Since the Baia Mare disaster in Romania in January 2000, the use of cyanide has been resisted. Germany passed a decree in 2002 prohibiting mines from using cyanide in leaching processes.

The process to concentrate gold using cyanide was developed in Scotland in 1887 and was used almost immediately in the Witwatersrand gold fields of the Republic of South Africa. Heap leaching with cyanide was proposed by the Bureau of Mines in 1969 as a means of extracting gold from lowgrade ores.

Cyanide has proven to be the most effective solvent for gold and silver, but it continues to attract negative publicity due to environmental concerns, even though mostly misinformed. Alternative processes are being sought to overcome this negative impression, which in some high profile cases can halt project development.

A case of deliberate ingestion of an electroplating solution containing gold cyanide is described. Despite the use of an antidote, and supportive treatment for cyanide poisoning, the patient died after 13 hours. Sublethal cyanide and high red blood cell gold levels suggest acute gold .

Gold electroplating is a much more diverse subject than silver plating. There are at least four different types of electroplating baths: acidic cyanide solutions, neutral cyanide, alkaline cyanide, and noncyanide baths (40,41).There are, however, hundreds of different formulations for these bath types.

Cyanide extraction of gold through milling of highgrade ores and heap leaching of lowgrade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metalcyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.

the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide (NaCN) is added and the cyanide ion forms a complex ion with the gold. This complex ion, [Au(CN)2], is readily soluble. Issues of gold extraction using cyanide:

10/06/2019 · Traditionally, gold mining has depended on harsh chemicals such as cyanide and mercury to extract gold from ore. This has left our planet with a legacy of toxic waste which is harmful to health and the environment. For over 50 years, the industry and leading research institutions have been trying to find such an alternative without much success.
