Role of cyanide in ore processing. Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889.
