The Metallurgy of Cyanide Gold Leaching – An Introduction ...

2014-10-20  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.
