This involves several crushing stages, followed by grinding stages. These crushing stages usually involve several unit operations in series, such as jaw crushers, cone crushers, hammer mills, and autogenous or semi autogenous grinding mills to reduce particle size from the scale of boulders down to several millimetres.

Other articles where autogenous mill is discussed: mineral processing: Grinding: 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.
