The Metallurgy of Cyanide Gold Leaching – An Introduction
Oct 20, 2014 A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all gold cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na [Au (CN) 2] + 4 NaOH. The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward

Biological treatment for the degradation of cyanide: A
May 01, 2021 For the recovery of gold we have the Elsner equation: (1) 4 A u + 8 N a C N + O 2 + 2 H 2 O ↔ 4 N a [A u (C N) 2] + 4 N a O H. The reaction for the recovery of silver is as follows: (2) A g 2 S + 4 N a C N + H 2 O ↔ 2 N a [A g (C N) 2] + N a S H + N a O H
