Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:
Sod ium cyanide has been used in the extraction of gold from ore for over a century. Today it is still considered the most efficient extraction method – with sodium cyanide used in the leaching process in most gold mining operations. Orica is one of the largest producers of sodium cyanide for the mining .
Sodium cyanide is also known as cyanide of sodium, cymag, hydrocyanic acid sodium salt. It is a white powder or solution in water. Liquid cyanide contains 30 per cent cyanide while the solid is 98 per cent pure in Australia (though lower grades are produced overseas).
Cyanide in mining and industrial wastewaters has been around from the beginning, including electroplating processes. This presentation reviews a number of current processes, and in particular, offers new technologies for improvement in cyanide destruction by the most common process, using sodium hypochlorite.
About Sodium Cyanide. Sodium Cyanide (a.k.a. NaCN) is an inorganic salt, extremely toxic to humans, due to its binding with the Fe3+ ion in the hemoglobin, disabling the use of oxygen by the cells. It is a white cubic crystalline solid also known as white cyanide, has been the metal cyanide with the greatest commercial importance.

Sodium cyanide can be rendered safe or detoxified by treating it with hydrogen peroxide (H 2 O 2), which gives the much less toxic sodium cyanate (NaOCN) as the product. NaCN + H 2 O 2 → NaOCN + H 2 O. Uses: The main application of this toxic compound is in the mining industry, where it is used to extract gold and other precious metals from ...
The "International Cyanide Management Code For the Manufacture, Transport, and Use of Cyanide In the Production of Gold" (Cyanide Code) was developed by a multi-stakeholder Steering Committee under the guidance of the United Nations Environmental Program (UNEP) and the then-International Council on Metals and the Environment (ICME).
Mar 07, 2016· 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. Since a tailings dam burst at gold mining company Aurul's Baia Mare mine in Romania in 2000, leaking cyanide into the Somes River and killing ...
Sodium Cyanide Sodium Cyanide's Significant Role in Gold and Silver Mining. As the demand for gold and silver grows, the need for mining operations that run efficiently and consistently grows with it.

Here is a complete recipe on how to make sodium cyanide.. First, 100 g of sodium hydroxide is mixed with 43g of cyanuric acid and 12g of carbon. This is heated to .
Jul 03, 2015· Of those methods, the 'Cyanide Leaching Process' (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium cyanide solution. This article will give a general overview about how this important, 120 year old gold mining process works.
Nevada Operations Cyanco started producing liquid sodium cyanide in 1990 at a single plant in Winnemucca, Nevada. The plant was constructed for the sole purpose of providing this strategic chemical to the mining industry in northern Nevada. This state-of-the-art, zeroSee More
Sodium cyanide is used throughout the world, primarily as a reagent in the mining industry for the isolation of precious metals. Close to 90% of sodium cyanide is used for gold and silver processing in the North American markets and around 78% is used for this purpose worldwide.
Nov 28, 2016· Cyanide has been used in the mining industry in some iteration since all the way back in the 1880s. Today, the term "cyanide" conjures grisly images of a toxic poison, but in reality, cyanide is a naturally occurring element found everywhere from fruit to nuts to bugs.
Sodium Cyanide. Sodium cyanide is a white, water-soluble solid which is available in briquette form. It is used in the mining industry as cyanide has a great affinity for metals and this is the most common economically viable method for gold extraction.
Mitigating risk and keeping operations running smoothly is essential in the mining industry, and sodium cyanide management is no exception. Although sodium cyanide is a commonly used reagent in mining, most mines do not have a dedicated cyanide safety .
Aug 18, 2015· Sodium cyanide is used industrially across the globe, most frequently in the mining of gold. Although most of us have the traditional imagery of a .
Jul 04, 2013· Orica, one of the largest global producers of sodium cyanide, manufactures and delivers cyanide for gold extraction in the mining industry. Find out more at ...
Sodium Cyanide is used as a reagent in the mining industry for the extraction of minerals, primarily gold and silver. It is mostly used as a flotation reagent in the mining industry. The processing of gold and silver accounts for almost two-thirds of sodium cyanide application.
Sodium cyanide cost contributes an estimated 5% towards cash costs for most mining companies, and it is tied to long-term profitability. As a result a reliable, low cost sodium cyanide supply partner is an important part of any gold mining company.
Gold Mining with Cyanide REPORT ON I-147 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.
