The return of 100400% of the ore mass to the mill typically reduces the retention time of the material inside the mill increasing the grinding capacity, improving the energy efficiency, resulting in a more homogenous ground product (Jankovic et al., 2013) . Artisanal miners frequently grind in open circuits with the gravity separation equipment.

Only a few prospectors among the many thousands who searched the western part of the United States ever found a valuable deposit. Most of the gold mining districts in the West were located by pioneers, many of whom were experienced gold miners from the southern Appalachian region, but even in colonial times only a small proportion of the gold seekers were successful.
