What Is The Role Of Cyanide In Mining Miningfacts

What Is The Role Of Cyanide In Mining Miningfacts Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. 3 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.Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. 3 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.Apr 21, 2021 Annually, 1.1 million metric tons of hydrogen cyanide are produced, with approximately 6 used to produce cyanide reagents for gold and silver processing. Cyanide usage is popular because it easily combines with many metals especially gold. In gold mining, a sodium cyanide solution is generally used to leach gold from ore.A weak solution containing a quantity of sodium cyanide 0.015 percent average is percolated over crushed ore to dissolve the gold. The leach solutions are carefully buffered with an alkali usually lime to prevent the possible generation of hazardous hydrogen cyanide gas. The gold bearing solution is collected and the gold removed.
