Because of this important role of pH, lower pH releases cyanide into free cyanide, or alkaline pH increases cyanide leaching capacity of gold 116. Therefore, mining operations usually try to keep the pH of cyanide solution between 95 and 11, of which 105 is the most suitable for leaching 117. In addition, the alkaline pH value of cyanide solution can improve the leaching capacity of cyanide solution
