gold mining process control using cyanide

Cyanide Use in Gold Mining Earthworks. Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; 1872 Mining ...

Potassium dicyanoaurate - Wikipedia

Potassium dicyanoaurate is produced in the cyanide process variant of gold mining. The chemical reaction for the dissolution of gold, the "Elsner Equation", is: 4 Au + 8 KCN + O 2 + 2 H 2 O → 4 K [Au (CN) 2] + 4 KOH In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au (CN)−
