Influence of moisture levels on iron and manganese within ...

The moisture content of soils and near-surface sediments have a dominant control on biogeochemical reactions controlling the fate or compounds ranging from organic carbon to metal contaminants. Within variably saturated near-surface sediments, the particle size distribution, mineralogy, local climate, hydrology, landscape and depth all influence moisture content.

Iron Ore Fines (IOF) are a product of iron ore, commonly having a particle size less than 6.3 mm, which is transported around the world in bulk carriers. Since the holds of bulk carriers are not designed to carry liquid, if liquefaction of IOF or other minerals occurs, it can cause the vessel carrying the cargo to

Quantification of Moisture Contents in Iron and Manganese Ores

The standard method to determine the total iron content in ores is the ISO 2597-2:2008, which makes use of a titrimetic method with potassium dichromate as the titrant. Prior the analysis, the material should be dried in order to remove the moisture and hence the results can be given on a dry sample basis.

Typical seagoing motions also caused no failures in the samples of IOF even when the moisture content was above the TML, determined by the MPFT, but under high levels of transverse accelerations with no vertical accelerations, failure can occur if the moisture content is above the TML (Iron Ore Technical Working Group, 2013b).

DescriptionApplicationShipment / Storage / Risk FactorsIron Ore (fines)Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour 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)) or siderite (FeCO3). Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as \"natural ore\" or \"direct...
