  • MEI Blog: Is the Autogenous Mill a Cornish invention?

    Feb 8, 2016 An AG mill is a tumbling mill that uses the ore itself as grinding media. 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
