    Grinding refractory gold ores to below 20 microns and finer whilst liberating more gold also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery.
