MEI's Barry Wills Is the Autogenous Mill a Cornish invention

Feb 08, 2016 The ore must contain sufficient competent pieces to act as grinding media and preferably be high specific gravity which, for example, favors AG milling of iron ores and early deployment of AG mills can be attributed primarily to a need in the iron ore industry to economically process large quantities of ore in the late 1950s.

Processing of Magnetite Iron Ores Comparing Grinding

Processing of Magnetite Iron Ores Comparing Grinding

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding 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 and magnetite in coarse magnetic separation.
