Autogenous mills are not common as the small benefit gained in the specific circumstances of differential ore hardness are relatively rare, and unless there is a reason from a metalurgical perspective that the presence of iron is undesirable a faster and more consistent grind can be achieved with a semi-autogenous (SAG) mill.

Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added
