Iron overload is known to occur in the West European and American population due to the consumption of iron-rich diets. On the other hand, genetic disorders leading to iron overload are also known. Iron overload leads to increased peroxidation and disruptive disintegration of lipid-rich membranes, and predisposes humans for an enhanced risk of cancer induction. In experimental animals iron ...

In the present study, leaching behavior of scandium from limonitic laterites under sulfation roasting–water (SAL) was explored. The mineralogical analysis showed that associated with iron phase. roasting temperature played an important role in phase conversion during process. With increase 100 to 800 °C, (goethite, magnetite, and hematite) gradually converted monoclinic Fe2(SO4)3 (400 °C), then...

Ferronickel products obtained from the traditional process used to treat limonite nickel laterite usually assay very low-grade Ni, only 3–5% Ni due high Fe/Ni ratio of laterite. This paper describes an investigation conducted upgrade laterites for preparation ferronickel by using selective reduction smelting technology. By means thermodynamic calculations and experiments, separation mechanism b...

[1] Sediment cores from the intertidal zone of Waquoit Bay (Cape Cod, Massachusetts) yielded iron oxide-coated sands in the subterranean estuary, which underlies the head of the bay. The oxides were dark red, yellow and orange colors and are formed by the oxidation of ferrous iron-rich groundwater near the groundwaterseawater interface. Within these iron oxide-rich sediments, the concentration ...

The Biwabik Iron Formation is a approximately 1.9 billion year-old sequence of iron-rich sedimentary rocks that was metamorphosed at its eastern-most extent by approximately 1.1 billion year-old intrusions of the Duluth Complex. The metamorphic recrystallization of iron-formation locally produced iron-rich amphiboles and other fibrous iron-silicate minerals. The presence of these minerals in ir...

The mineralogy and chemistry of the less than 20μm fraction of marine sediments at Morphou Bay, north-west Cyprus, are presented to characterise fine-grained sediment supplies from basic and ultrabasic rocks of the Troodos Massif within a typological setting. The sediments comprise a mixture of smectite, illite, kaolinite and iron rich chlorite. They also contain amorphous iron oxides/hydroxide...

The evolution of the martian core is widely assumed to mirror the characteristics observed for Earth's core. Data from experiments performed on iron-sulfur and iron-nickel-sulfur systems at pressures corresponding to the center of Mars indicate that its core is presently completely liquid and that it will not form an outwardly crystallizing iron-rich inner core, as does Earth. Instead, planetar...
