The unmelted iron ores still contain non-reduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave non-reduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can be almost completely reduced.

Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

Before the iron ores enter a blast furnace, it undergoes 'sintering' which turns the pristine iron ore into more compact and appropriate sizes. The sintered iron ores become 'sinter.' The iron ores that come in just the perfect size right from the extraction are called 'sized lump.' The ores in microscopic scales are pelletized, which are called 'pellets.' Steelmaking utilizes

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace.

In blast furnaces iron ore (Fe 2 O 3) is reduced to metallic iron (Fe). Regular reduction agents are materials like coke, coal and/or heavy oil. Yet, steel producers such as British Steel (UK) and Stahlwerke Bremen (Germany) sought alternative agents, such as plastics waste. Stahlwerke Bremen (in the mean time known as ArcelorMittal Bremen) is using this source on a regular basis and others
