Gold cyanidation Wikipedia

Dec 15, 2003· The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au(s) + 8 NaCN(aq) + O 2 (g) + 2H 2 O(l)→ 4 Na[Au(CN) 2](aq) + 4 NaOH(aq) . In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au(CN) − 2 ion.. Application. The ore is comminuted using grinding machinery. .

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.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
