Abstract. cyanide extraction of gold through milling of highgrade ores and heap leaching of lowgrade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (nacn), free cyanide, and metalcyanide complexes. some milling operations result in tailings ponds of 150 ha and larger.See Details
Abstract. highly toxic sodium cyanide (nacn) is used by the international mining community to extract gold and other precious metals through milling of highgrade ores and heap leaching of lowgrade ores (korte et al. 2000). the process to concentrate gold using cyanide was developed in scotland in 1887 and was used almost immediately in the.See Details
Annually, 1.1 million metric tons of hydrogen cyanide are produced, with approximately 6 used to produce cyanide reagents for gold and silver processing. cyanide usage is popular because it easily combines with many metals especially gold. in gold mining, a sodium cyanide solution is generally used to leach gold from ore.See Details
Cyanide (cn –) has been used since 1889 to recover gold from hard rock. as sodium cyanide (nacn), it reacts with gold, oxygen (o), and water (h 2 o) to form a gold cyanide complex (na. au (cn) 2 ) and sodium hydroxide (naoh). the chemical reaction dubbed the elsner equation, named after its discoverer, is shown below:.See Details
