The use of cyanide in gold mining
The use of cyanide in gold mining In recent years the use of cyanide in gold mining has become the dominant means by which gold is extracted from a body of ore The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body’s gold In contrast, leaching finely ground ore with cyanide can recoverAnalysis 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 Aurul’s Baia Mare mine in Romania in 2000, leaking cyanide into the Somes River andShould cyanide still be used in modernday mining?
