Autogenous Grinding Mill Process Iron Ore

The Brazilian iron ore resources are shifting from high grade ores with good liberation at coarse sizes, to lower grade ores with good liberation only at finer sizes, requiring grinding down to a fine size to liberate and concentrate. Considering the very large throughputs required in the plants it is important to ensure the long-term economic and energy feasibility of this process

    Feb 24, 2015 Historically, the lowest operating cost for fine-grained ores was achieved by multi-stage, fully autogenous grinding (Koivistoinen et al, 1989) with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel

    In autogenous grinding, a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short length (the ratio of diameter to length is approximately 3). Ore with pieces having dimensions up to 300 mm (sometimes, up to 600 mm) is loaded into the mill

    Dec 30, 2013 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
