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 (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Iron Ore: Sedimentary Rock - Pictures, Definition & More,Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.Specifications guide Iron ore - S&P Global,The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world. These are the timestamps used for Platts iron ore assessments. Data reported at or after these timestamps is not considered in the assessment process.

Lumpy/Fine Ore: Iron Ore is traded in lumps (i.e. sized ore) or in fines. Production/availability of lumps is limited by virtue of the natural occurrence and also because of generation of lot of fines during crushing of large lumps present in the run-of -mines.Iron ore pricing explained | Metal Bulletin,Iron ore is a non-fungible commodity, and its quality varies. To help facilitate price adjustment for differences between expected and delivered product specifications, PRAs have developed value-in-use (VIU) indices for the key price-affecting chemical components of iron ore - iron, silica, alumina and phosphorus.Safe carriage of Iron ores & other iron concentrates in bulk,Most iron ore is carried in Cape-size ships, i.e. larger than 80,000 tonnes deadweight, although ships of this category are often much bigger and are generally in the region of 170,000 tonnes deadweight. However, the largest are presently of about 360 metres in length,,ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G,,to the major groups of ore-forming processes are given in Table 1.

Generally carry grain, coal and iron ore from US ports.Guide to the types and sizes of dry cargo and tanker ships,Bulk Carriers: As their name implies, these vessels mainly carry bulk cargoes (like coal, iron ore, grains, minerals etc) while it is not uncommon general cargoes (e.g. bagged cargoes and steels) to be loaded also in bulk carriers of smaller size. These vessels are single-deckers and they are not able to load containers. Their hatches have very large openings so as the vessel to be

Vessel Size Groups (in deadweight tons) Source: UNCTAD (2000) Review of Maritime Transport. Major ship size groups include: Handy and Handymax: Traditionally the workhorses of the dry bulk market, the Handy, and the more recent Handymax types are ships with less than 60,000 dwt.The Handymax sector operates in a large number of geographically dispersedCapesize - Wikipedia,Ships in this class are bulk carriers, usually transporting coal, ore and other commodity raw materials. The term capesize is not applied to tankers.The average size of a capesize bulker is around 156,000 DWT, although larger ships (normally dedicated to ore transportation) have been built, up to 400,000 DWT.The large dimensions and deep drafts of such vessels mean thatIron ore (fines) - Cargo Handbook - the world's largest,,Description.
