Gold Metallurgy and Leaching Process

2020812&ensp·&enspLeaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes

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.
