ensure that it is fine enough to liberate as much gold as economically possible, typically 60 to 80% finer than 200 mesh (74 microns). The ground ore and mill water (pulp), is leached by mechanically agitating it in a series of tanks. During the agitated leach, additional cyanide is added along with air and/or oxygen which are necessary
