Gold Leaching Agent Compared to Cyanide in Gold Processing

Cyanide leaching is a process in which solid natural gold in ore or beneficiation product forms a gold-cyanide complex dissolved in water under the combined action of a leaching agent, an oxidizing agent and a base, that is, a phase transformation process of solid phase gold. Chemical reaction formula for gold leaching: 4Au+8KCN+2H2O→4KAu (CN ...
