distinguished by the production of high-quality liquid hot metal on the basis of directly charged iron ore fines, and coal as the reductant and energy source. A key feature of the FINEX® Process is that iron production is carried out in two separate process steps. In a series of fluidized-bed reactors, fine iron ore is reduced to direct
al hot-metal pretreatment methods using torpedo ladle cars or mol-ten metal ladles as the reaction vessels enabled stable production of low-P, low-S steels, but it required desiliconization at a prior stage, and as a result, the thermal allowance for the decarburization in con-verters decreased and the scrap ratio was significantly restricted. As

of ICE's entry into iron ore is underscored in the following chart: More directly, relational pricing can exist between iron ore and steel (known as the "metal spread") and iron lump to steel (the "hot metal spread"). These 'lumps' are the intermediate stage between iron ore and pig iron. IRON ORE MARKET STATUS AND EVOLUTION
Chinese steelmakers exhibited an increasing preference for iron ore with higher iron content and lower silica and alumina levels, for furnaces to produce less slag and more hot metal per ratio of ...
agent. The metallic iron produced by such a furnace contains a relatively high proportion of carbon (4%) and is passed to the steelmaking process as a liquid at approximately 1450C, called "hot metal". Refining: Steelmaking The refining of iron to make steel is where the carbon content of hot metal is lowered, usually to

Iron making. Iron ore is mined in around 50 countries – the largest producers are Australia, Brazil and China. Around 98% of iron ore is used in steel-making. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
It is likely that excess domestic scrap supply will, in the first instance, be used to reduce hot metal ratios in oxygen furnaces, yet the implications for iron ore demand are similar. While total global demand for iron ore is expected to peak around 2025, the decline in the ensuing decade will likely be gradual.

The iron ore at room temperature is loaded from the furnace top, which is located at the height position between 22 and 23 m in Fig. 4(a), and it is heated through the heat exchange with the gas. The iron ore starts melting when the temperature reaches around 1200 °C, which leads to the decrease of ore volume ratio at the height position between 2 and 3 m in Fig. 4(b).
