Bulk Iron Ore
Iron Ore is a rock containing iron-rich compounds and forms the basic raw material in the manufacture of steel and iron products.
There are many varieties of iron ore, such as hematite and magnetite, mined throughout the world and shipped, especially in large ships, to industrial regions worldwide in the form oi fines (dust) or in lumps; can be very dusty or, alternatively, attract moisture up to 16% of its dry weight.
The export trade is dominated by Australia and Brazil, whilst the largest importers are China, Japan and the EU countries, although there are many smaller exporters and importers engaged in this large market handling considerable quantities and employing panamax sized ships or above.
In order to ship more concentrated product and to avoid the unnecessary carriage of waste material, there are various methods of partly refining iron-ore. Each of these partly processed products has its own transport difficulties and each requires careful and specialized handling.

Bulk Iron Ore Shipping
Most of the world’s metals are produced from smelting mineral ores, such as iron ore or bauxite, and in most cases the smelting is carried out at some distance from the mine.
Iron Ore, for the production of iron and steel, is the single largest product traded within this group. Most ores are a good deal more dense than coal (coal has a stowage factor of around 50 cubic feet per tonne compared with about 14 cubic feet per tonne for a typical iron ore) and at one time ore was carried in specialized bulk carriers with relatively small holds on top of large double-bottom ballast tanks to cope with this characteristic.
Nowadays, ores are carried for the most part in general purpose bulk carriers, most of which have flexible ballasting arrangements and strengthened bulkheads to allow them to carry a much wider range of bulk cargoes.
Iron Ores are normally loaded and discharged at specialized terminals.
Typically, an ore loading terminal will have deep water alongside, to allow large bulk carriers to be loaded and extensive stocking areas feeding cargo into the ship by a series of high- volume conveyors.
Specialized gantry-type grab fitted cranes will usually carry out discharging, with cargo being removed from the quay by conveyor belts to storage compounds.
Numerous minerals capable of transport by sea can be collated by the uses to which they are put. Thus ores used in the iron and steel industries and the compounds and alloys created from these ores can legitimately form the Ferrous Ores Family.
From its sheer volume alone, by far the most important of all minerals is iron-ore, moved in bulk in huge quantities from deposits to iron and steel works around the world.
Other Ferrous Ores, despite being more limited in volume nevertheless play their own important role in this market and are also normally shipped in bulk, although in somewhat smaller ships than the large ships commonly employed to serve the deep-water facilities enjoyed by the iron-ore trade.
Mixture and part processing of these minerals produces compounds and alloys which in turn form cargoes moving between iron and steelworks perhaps many hundreds of miles apart. Because of the enormous quantities of product involved, it is inevitable that Specialised Ore Charterparty Forms have evolved to serve the trade.
Some of these Specialised Ore Charterparty Forms are published by particular corporations connected to the business of mining and/or marketing ore, others cover a particular type of ore, possibly from a certain area or port such as The Iron Ore C/P 1961 – ex Lower Buchanan, Liberia – codenamed LAMCON. Yet other Ferrous Ores and related cargoes are fixed on multi-purpose documents such as the ubiquitous GENCON Charterparty.

b) The Japan Shipping Exchange Iron Ore Charterparty – NIPPONORE
c) BIMCO’s General Ore Charterparty, 1962 – GENORECON
Ferrous Ores and Alloys are heavy and dense, thereby occupying only a small space for every tonne. It is important, however, that the carrying ship’s cargo compartments can safely sustain such heavy cargoes, and most modern bulk carriers engaged in these trades will have ore-strengthened tank-tops.
Although the angles of repose of Ferrous Ores are usually greater than the critical 35°, it will usually be necessary to trim such cargoes so as to cover the entire tank top area, both to make the cargo less likely to shift at sea and to spread weights more evenly on the load-bearing parts of the ship.
Some of the largest bulk carriers, together with combination-ships (ore/oilers and oil/bulk/ore ships) will be found engaged in moving iron-ore, some of these ships built specially for the carriage of this commodity with small, strong holds, limited by lack of cubic capacity from carrying a full deadweight of lighter cargo such as coal.
Such ships are termed ore-carriers and because of their lack of trading flexibility, are normally employed in the carriage of iron-ore on a long-term basis.
Because of the immense volume of iron-ore required by world industry, much of which must be moved at sea, and because of the value of the commodity, the seaborne trade benefits from economy of scale; deep-water ports and berths being served by large ships, often of 100,000 tonnes deadweight or more, loaded and discharged by sophisticated port equipment in a short time.
Other Ferrous Ores and Alloys are restricted to smaller tonnage and are moved in smaller ships, often from less well-equipped loading ports. If loaded in wet condition there will inevitably be some weight loss on the cargo out-turn but, if dry, ores can be very dusty.
Generally, however, Ferrous Ores and Alloys; with certain exceptions, form safe non-hazardous cargoes, provided the great weights are taken into account, and the ship is not unduly stressed during loading and discharging.
What is Iron Ore?
Iron ore is a natural mineral that contains iron, an essential element for various industrial applications, particularly in the production of steel. It is the raw material used to extract metallic iron, which is primarily found in the Earth’s crust in the form of iron oxides, such as hematite (Fe2O3) and magnetite (Fe3O4).
Iron Ore Uses and Applications
Iron ore is a vital resource for modern society and has numerous applications, with the most significant being steel production:
- Steel production: Iron ore is the primary raw material used in the production of steel, an alloy of iron and carbon. Steel is used in various industries, including construction, automotive, aerospace, and manufacturing, due to its strength, durability, and ability to be shaped into various forms.
- Pig iron and cast iron: Iron ore is also used in the production of pig iron, an intermediate product obtained by smelting iron ore in a blast furnace. Pig iron can be further refined into steel or used to produce cast iron, a brittle but strong material used in the manufacturing of pipes, machinery, and automotive parts.
- Iron-based chemicals: Iron ore can be used to extract iron for the production of iron-based chemicals, such as ferric chloride (FeCl3) and ferrous sulfate (FeSO4), which are used in water treatment, dyeing, and other industrial processes.
- Cement production: Some types of iron ore can be used as a component in the production of cement, where it serves as a source of iron oxide and contributes to the strength and durability of the final product.
To extract iron from iron ore, several processes are used, including:
- Mining: Iron ore is extracted from open-pit or underground mines, depending on the depth and location of the deposits. The mining process involves drilling, blasting, and excavating the ore, followed by transportation to processing facilities.
- Crushing and screening: The extracted iron ore is crushed and screened to separate the various size fractions and remove impurities. This step is necessary to prepare the iron ore for further processing.
- Concentration: Depending on the iron ore’s composition, it may undergo a concentration process to increase the iron content and remove waste materials. This can be done through methods like gravity separation, magnetic separation, or flotation.
- Pelletizing: Iron ore fines (small particles) are often pelletized to create uniform-sized pellets that can be easily handled and processed. The pelletizing process involves mixing the iron ore with a binder and rolling the mixture into small balls or pellets.
- Smelting: The iron ore is smelted in a blast furnace, a large, vertical furnace that uses coke (derived from coal) as a fuel and reducing agent. The smelting process involves heating the iron ore to high temperatures, reducing the iron oxide to metallic iron, and producing pig iron.
- Refining: The pig iron is further refined to produce steel through processes like basic oxygen steelmaking or electric arc furnace methods.
Iron ore plays a crucial role in modern society, providing the raw materials needed for various industries and infrastructure projects. The global demand for iron ore remains high, driven by the need for steel in construction, manufacturing, and other sectors.
