Cyanidation of Gold - Crushers, Ball Mills, Flotation ...

Cyanidation of gold is a gold extraction method from the gold ore. It has been more than 100 years since the cyanide solution was used to leach gold from ore in 1887.The gold-containing solution obtained by cyanide leaching is called pregnant solution. It is commonly used to deposit gold mud by zinc replacement method or electrolysis method. Gold can be obtained by melting gold mud.
