Cyanide Use in Gold Mining

Cyanide's efficiency makes mining more wasteful Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grad 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;...

Extraction of gold using cyanide

To make gold soluble sodium cyanide (NaCN) is added and the cyanide ion forms a complex ion with the gold This complex ion, [Au(CN)2]-, is readily soluble Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough dos Free cyanide is cyanide ion (CN-) and hydrogen ....
