The work of Freer, following on from Bohme and Kilian, showed how successful this route is for optimizing the mill power draw and throughput of a gold ore mill. Given the breakage characteristics of most ore waste systems and widespread use of autogenous and semiautogenous mills, the potential for this type of sorting appears enormous.

Autogenous grinding (AG) and semiautogenous 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. Semiautogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
