Safe carriage of Iron ore & other iron concentrates in bulk. Iron ore is used for the production of metallic iron in steel-making. Although some 45 countries export natural iron ore resources, seven countries provide 75% of the total exported. The two largest exporters are Brazil and Australia, with about 33% of total world exports each.
It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.
Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites.
Sinter plants recycle iron ore fines from the raw material storage and handling area, waste iron oxides, and pollution control systems. Iron ore may also be processed in on-site sinter plants.
