Risk Management (RM) would be applied to assess the level of the risk companies, workers and communities are expose to as a result of transportation, usage and disposal of cyanide in gold .

Cyanide has been used in the process of mining gold since 1887. When a dam burst at a gold mine in northwestern Romania in 2000, contaminated wastewater poured into tributaries of a major waterway in Hungary, threatening the people, animals and environment of Serbia, Bulgaria and Romania.
the environment from the use of cyanide in gold mining, and reducing community concerns about its use. The objectives of the Code as identified by the Committee are: w To protect workers, communities and the environment from adverse effects of cyanide. w To improve cyanide management. w To be used by large and small gold mining companies, cyanide manufacturers and transporters.
The International Cyanide Management Code – It's Not an Oxymoron. Winter 2005/2006. Author: Edward M. Green. When most people think about gold mining, they envision an oldtime miner panning for nuggets in a stream.
Mining Cyanide Destruction The destruction of cyanide in gold tailings is a crucial part of metallurgical recovery of gold. Many jurisdictions have strict regulations controlling the destruction of cyanide and metal cyanide in tailings prior to discharge into the environment.
26 Mining Environmental Management July 2010 INNOVATION T HE cyanide leaching process, introduced to the goldmining industry about 120 years ago, was at the forefront of the technological revolution in the industry
In contrast the banning of mining would not eliminate the use of cyanide as only about ten percent of its global production is used in the recovery of gold. Most is used in the manufacture of plastics, pharmaceuticals and other useful products.
we review the history of cyanide use in gold mining with emphasis on heap leach gold mining, cyanide hazards to plants and animals, water management issues associated with gold mining, and proposed mitigation and research needs.
Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore.
In early 2002, the committee completed the International Cyanide Management Code for The Manufacture, Transport and Use of Cyanide In The Production of Gold. As conceived by the steering committee, the Cyanide Code was more than a guide to best management practices for the use of cyanide in the production of gold.
As a founding signatory of the International Cyanide Management Institute (ICMI) and with a track record of more than 25 years, Australian Gold Reagents Pty Ltd (AGR) manufactures solid and solution sodium cyanide at modern, safe production facilities in Western Australia.
At the Ovacik gold mine (), gold is extracted from crushed ore using three years, the mine has produced approximately 11 ton of gold as well as 12 ton of silver,,,, .Cyanide was first used in the Turkish mining industry in 1987 at a staterun silver plant.

In this account, we review the history of cyanide use in gold mining with emphasis on heap leach gold mining, cyanide hazards to plants and animals, water management issues associated with gold mining, and proposed mitigation and research needs.
Why Is The Management Of Cyanide Important? Each year, the mining and electroplating industries rely on large amounts of useful, but toxic cyanide. Unfortunately, voluntary or involuntary release of this compound into surface waters does occur, posing a severe threat to animals, humans, and aquatic life.
Gold Mining with Cyanide REPORT ON I147 Repeal of the Ban on Cyanide Heap Leaching in Gold Mining WHAT IS CYANIDE AND WHAT DOES IT DO IN THE ENVIRONMENT Cyanide is a general term, referring to various specific cyanide compounds. Cyanide (CN) itself is a simple, organic anion (negatively charged ion) consisting of carbon and nitrogen.

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in 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.
• Cyanide leaching and recovery of the gold, silver, or mercury from the ore; • Management of tailings (containing the finely ground material and liquid); • Carbon stripping and regeneration; • Refining o Electrowinning or zinc precipitation; o Mercury Retorting; and o Refining.
