· Banded iron formations (BIF) and iron ore are globally important resources of iron that have very distinctive textures. Wellpreserved BIF contain ironrich bands consisting of iron oxides (, hematite, magnetite), iron silies (, stilpnomelane), and iron oxyhydroxides (, greenalite), that are interlayered with siliceous chert bands.
20/07/2015 · Iron Ore: Mineralogy, Processing and Environmental Issues summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (, production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.
Ironformation ores include primary and enriched varieties. Primary magnetiterich ores are generally lower grade (<40 wt% Fe total) but have larger combined resources and reserves compared with enriched ores that have grades of 40 to 72 wt% Fe ores include early hypogene (magnetite, crystalline hematite) and later supergene (goethite–hematite) ore types.

· The iron ore formation started over billion years ago when abundant iron was dissolved in the ocean water which then needed oxygen to make hematite and magnetite. The oxygen was provided when the first organism capable of photosynthesis began releasing oxygen into the waters. This oxygen combined with dissolved iron to form hematite and magnetite. These then deposited on .
