May 08, 2019 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.Gold is found in very low concentrations in the ores from which it is mined. Generally, to recover the gold requires separation of it from the associated minerals in the ore, which could be achieved by selectively dissolving the gold in a suitable lixiviant. Worldwide, majority of gold is extracted from it ores using cyanide as a lixiviant.
