Bedded sedimentary iron ore deposits are thought to occur as a result of mineral precipitation from solutions present during the Precambrian period (2.6 to 1.8 billion years ago). The largest bedded sedimentary iron ore deposits in the United States are found in banded iron-formations and ironstones, which are more fully described below.
The iron occurs as residual or secondary ore caps resting on Precambrian banded iron formation. The caps are as a result of tropical weathering and leaching of underlying quartz-magnetite rocks and the iron rich amphibolites. Estimates 136. Abu Bakarr Jalloh et al. /
The "pig" iron produced by the blast furnace has a relatively high carbon content of around 4-5%, making it very brittle, and of little commercial use.Some pig iron is used to make cast iron.
