Cyanide Chemistry International Cyanide

The process of extracting gold from ore with cyanide is called cyanidation. The reaction, known as Elsner's Equation, is: 4 Au + 8 CN-+ O 2 + 2 H 2 O = 4 Au(CN) 2-+ 4 OH-Although the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron .
