The iron formation is overlaid by the slates of the Michigamme formation. The physical structure of the ores on the Marquette range is excellent, none of them having a fine enough structure to be objectionable to furnace men. The hard ores are used in lump form in the open-hearth processes; they are crushed for use in the ordinary blast furnace.

Hematite: A primary ore of iron and a pigment mineral - Geology

Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Estimating the lump to fines composition split in iron ore …

Iron ore is mined, crushed and separated into lump and fines components, which are sold as separate products. Quality (and therefore value) depends upon the shipped composition of each product matching a target composition vector, in iron and in several other minerals. Each day, ore is selected for mining to meet these target grades.
