Improving the process performance of gold cyanide

In the gold mining industry today, cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon Fleming et al. 2011. Typically, the carbon in pulp CIP or carbon in leach CIL process is used for gold recovery. These
