  • The Metallurgy of Cyanide Gold Leaching – An Introduction

     · A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na[AuCN 2] + 4 NaOH. The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward
