· Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route—or through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.

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 ...
