Cyanide leaching is a method that has transformed the gold mining industry with its effectiveness and efficiency. The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution. From this solution, gold is later recovered, often by carbon adsorption.
