Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in …

Effect of Gold Particle Size on Rate of Dissolution

Under what might be considered ideal conditions with respect to aeration and agitation, researchers found the maximum rate of dissolution of gold to be 3.25 mg/cm2/hr hour. By calculation this is equal to a penetration of 1.68 microns on each side of a flat gold particle, or a total reduction in thickness of 3.36 microns/hour.
