Rio Tinto Iron Ore – Geology

Key characteristics of Marra Mamba ores include a lower phosphorus content compared to most Brockman ores and a higher loss on ignition which reflects the different goethite mineralogy exhibited in Marra Mamba deposits compared to Brockman ores.

Iron – Wikipedia

Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to the most common isotope of iron) is the last nuclear fusion reaction that is exothermic.

Arrowstar Proposed Ground Geophysics Program on Rannie Lake, Labrador Iron Ore Property

Typical of the Knob Lake Range, Schefferville area, there are soft iron ores (direct shipping ore) composed of friable fine-grained secondary iron oxides – hematite, goethite, limonite – formed by supergene leaching and enrichment of the weakly metamorphosed cherty iron formation.

Science Daily – Archaeologist 'Strikes Gold' With Finds Of Ancient Nasca Iron Ore Mine In Peru

"What we found is the only hematite mine, a type of iron also known as ochre, recorded in South America prior to the Spanish conquest. This discovery demonstrates that iron ores were important to ancient Andean civilizations.".

Steel Production Iron ore production is often used as an indicator of a nation's economic health. For years, China has produced the most iron ore of any country on Earth. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.

Geological ore deposits – Australian Museum

The iron and manganese ores occur as distinct sedimentary layers alternating with iron and manganese-poor sedimentary layers – the whole mass is sometimes mined. Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF.

Metal Profile – Iron

One of iron's identifying characteristics is that it is strongly magnetic. Iron was likely originally discovered and extracted as a result of wood burning on top of iron containing ores. Iron's most troublesome characteristic is its tendency to form rust.

Iron This hard, black substance is magnetite, an important ore of iron and a very interesting substance in its own right, which will be considered further in connection with magnetism, where its structure will be explained.

Challengers to Clovis-age impact theory missed key protocols, new study finds – Communications

An interdisciplinary team of scientists from seven US institutions says a disregard of three critical protocols, including sorting samples by size, explains why a group challenging the theory of a North American meteor-impact event some 12,900 years ago failed to find iron- and silica-rich magnetic particles in the sit…
