Recovery of cyanide in the extraction of gold -

01/01/1993· Sodium cyanide is used in the extraction of gold from its ores. It, and many of its derivatives, are acutely toxic to humans and aquatic life. The awareness of environmental impacts has been heightened in the last decade, the effects of which are appearing in greater restrictions on discharges and emissions. A company has been recovering residual cyanide from its tailings in a

Tailings Dump and Cyanide Vats | Goldfields GuideCyanide process, also called Macarthur-forrest Process, method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide.The process was invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest. The method includes three steps: contacting the finely ground ore with the cyanide Gold Extraction From Tailings Without CyanideGold Extraction From Tailings Without Cyanide.

2. CYANIDE LEACHING Cyanidation uses solutions of sodium or potassium cyanide as lixiviants (leaching agents) to extract precious metals from ore. Cyanidation techniques used in the gold industry today include heap or valley fill leaching, agitation leaching followed by carbon-in-pulp (CIP), and agitated carbon-in-leach (CIL).

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 large numbers of fish in Hungary and Yugoslavia How is cyanide used in gold mining? - QuoraCyanidation is used to extract gold from a finely ground ore material in a mix with water at about 55% solids by mass. Gold extraction is always a surface processing based extraction process and has nothing to do with the process of Mining itself.
