CARRIAGE OF NICKEL ORE AND IRON ORE FINES : Detailed Bulletin

The Flow Moisture Point (“FMP”) is the percentage moisture content at which a flow state commences. From this figure, the Transportable Moisture Limit (“TML”) can be determined. This is 90% of the FMP, and represents the maximum moisture content of the cargo which is considered safe for carriage. The actual moisture content of the

10-03-2016  The point of change between the sample showing plastic deformation and not showing plastic deformation is referred to as the Flow Moisture Point (FMP). When a sample has been observed exceeding the FMP it is oven dried along with the previous sample, which should be just below the FMP, so that the GWC, of each, can be calculated.

For the ten iron ores samples, the average moisture determined by the TGA method was 0.18 ± 0.05%, whereas by the Karl Fischer method was 0.50 ± 0.14%. This large discrepancy in the contents determined by these two methods is believed to be real, and its origin is simply the fact that drying at temperatures close to 100°C does not eliminate all the adsorbed water in these samples.

STANDARD CARGO

In India, the flow moisture points for iron ore fines are generally tested in independent laboratories but these may lack the proper equipment or trained personnel to facilitate reliable measurement in accordance with the IMSBC Code. This has resulted in ships loading iron ore fines at Indian ports without accurate flow moisture points, creating

The blast furnace (BF) serves to produce pig iron from iron ore. The shaft of the BF is filled continuously from the top with layers of iron-bearing materials (iron ore, sinter, pellets, etc.) and coke. In order to reduce the iron oxides by carbon monoxide, heated air is fed into the BF in a counter-current flow. The

CARGO LIQUEFACTION AND DANGERS TO SHIPS

INTERNATIONAL REGULATIONS, RESPONSIBILITES and TESTS for AVOIDING CARGO LIQUEFACTION. 3.1 DEFINITIONS The definition of flow moisture point is the maximum water content, expressed as a percentage, at which a sample of cargo will begin to lose shear strength.

Transportable Moisture Limit (TML) Flow Moisture

A Flow Table Test (FTT) is conducted to find the FMP, with the TML calculated to be 90% of this figure. This is the maximum moisture level at which it is safe to ship the material; if the cargo is found to have a higher moisture content than the TML, it is strongly recommended that the cargo not be transported (unless the vessel is specially built for this).

Iron ore - Wikipedia

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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore
