    • Autogenous Grinding

    Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...
