In such cases the question arises as to why the iron and manganese are not intimately mixed in the form of a manganiferous iron ore, as would be expected if they had been precipitated together. Moreover, deposits sometimes occur which are composed largely.

Hematite: A primary ore of iron and a pigment mineral - GeologyThey comprise some of the largest rock formations in Earth's rock record. Many of the sedimentary iron deposits contain both hematite and magnetite as well as other iron minerals. These are often in intimate association, and the ore is mined, crushed, and processed to recover both minerals.

Minerals | Iron Ore

The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high-grade' ore, and banded . Another type of high-grade deposit is pisolitic limonite/goethite ore formed in ancient river channels, e.g. Yandicoogina, Hamersley Basin, Western Australia.

DSO deposits are typically rarer than the magnetite-bearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain significantly higher concentrations of penalty.

Huronian (Early Proterozoic) rocks hold the vast wealth of the iron formations in Michigan. As we have found, those rocks are broken, faulted, some even turned over backward. They are so cracked and shoved about, that the edges of ore bodies are separated by hundreds of feet, which makes mining difficult and the search.
