Gold Extraction Process 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 industryRead More
Kyrgyzstan Kumtor Gold Mine 1998 A truck carrying 2 tons of sodium cyanide crashed into the Barskoon river resulting in more than 2000 people seeking medical care Romania Aural Gold 2000 A tailings dam ruptured spilling 35 million cubic feet of cyanidecontaminated waste into the Tisza and Danube Rivers killing fish and poisoningRead More
The mining industry has historically used sodium cyanide for gold extraction since the latter half of the 19th century and remains the largest of the end users of the sodium cyanide market About 75 of global sodium cyanide consumption is used in the mining industry and about 90 of sodium cyanide consumption in North America is used in miningRead More
Nov 01 2020 · 1 Introduction Currently cyanide is the predominant lixiviant used to extract gold due to its strong complexation with gold and the technical simplicity of the leaching process Avraamides 1982 Habashi 1987 Marsden and House 2006However the use of cyanide can bring challenges in terms of environmental health and safety aspects Aylmore 2005 Laitos 2012Read More
Sep 01 2020 · The recovery of gold from the synthetic cyanidestarved glycine leachate in the presence of copper has been investigated using It was found that the adsorbed copper was mostly cuprous cyanide The effects of CN −Cu T and Gly Cu T molar ratios were not significant on the adsorption of gold and copper using IXOSAuC resin The gold recovery increased while the copper recovery decreased with the increasing initial goldRead More
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 lowgrade ore Since a tailings dam burst at gold mining company Auruls Baia Mare mine in Romania in 2000 leaking cyanide into the Somes River and killing large numbers of fish in HungaryRead More
stages lime and sodium cyanide are added to the pulp BHP Engineering 1991 Conventional carboninleach CIL cyanide leaching is used to recover the contained gold The carbon is recovered from the leaching tanks by using cylindrical screens with 08 mm round aperture The loaded carbon is stripped and the resultant solution isRead More
