Iron (Fe) Ore | Minerals, Occurrence » Geology Science

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.

Safe carriage of Iron ore & other iron concentrates in bulk

In the carriage of iron ore, the following precautions should be taken: Iron ores are heavy cargoes which occupy a small area for a large weight, ie they have a low stowage factor (between 0.240.80 m3/tonne). It is therefore important that the tanktop has sufficient strength to carry certain iron ores. If a bulk carrier loads a homogeneous ...
