Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
