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 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)−

When you ingest potassium cyanide, it mixes with the acid in your stomach to form hydrogen cyanide gas. The gas then goes to the body cells and prevents them from accessing oxygen, and they will eventually die. When the body cells die due to lack of oxygen, essential body parts like the heart and brain will stop functioning thus causing death.
