Iron Ore – MSK
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The Iron ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite [FeO (OH)], limonite [FeO (OH).n (H2O ...

The places where you can visit Mars on Earth | BBC Earth
The iron rich mineral called goethite transform in the acidic stream into hematite, which is also found on Mars. Scientists believe analysing hematite on Mars for organic matter preserved there may be a good way of finding evidence for life on the Red Planet.
Iron Oxide on Mars | Astronomy
This would account for Earth's huge liquid iron core and the powerful dynamo generating our planet's magnetic field, in turn protecting our atmosphere from the solar radiation that we expect blasted most of the unprotected Martian atmosphere away. If all goes well, our new robotic explorer Curiosity will safely descend to the Martian ...
Carbon Deposition Using Various Solid Fuels for Ironmaking ...
In this paper, we describe an innovative process involving iron reduction through chemical vapor deposition for appliions in the ironmaking industry. In our experiment, we produced tar vapors from pyrolysis of various solid fuels, including highgrade bituminous coal (HGC), lowgrade lignite coal (LGC), and biomass palm kernel shell (PKS), and decomposed these vapors into gases, .
