  • Grinding Iron Ore in a Wet Autogenous Mill

    2020-6-29  The Cretaceous plant at the Hill Annex mine of the Jones Laughlin Steel Corp. was designed with a wet autogenous mill for grinding low grade iron ore so that it could be concentrated by spirals and flotation cells. The plant, on the west end of the Minnesota’s Mesabi Range, went into operation in June 1961, and preliminary operating and metallurgical information describing the

  • Developments in iron ore comminution and

    As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower ...
