Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and …

Figure 1: Steelmaking byproducts for blast furnace (BF), basic oxygen furnace (BOF) and electric arc furnace (EAF) processes. Source: World Steel Association (worldsteel) The first step in the production of steel or cast iron alloys is the reduction of iron ore—which contains iron oxide and gangue or mineral impurities—to unrefined, reduced iron form.
Already in the 1970s and 1980s the COREX process was developed. In this process coal (to replace the majority of coke) is used to create CO and H 2 to reduce the iron ore and melt the iron. By its more efficient energy utilisation, less CO 2 per tonne of HM is produced. Worldwide a few commercial COREX plants were built, but their HM production ...
Desulphurization of hot metal with lime is the most economic process for removing sulphur before charging to the BOF. Formed sulphides from lime are very stable.
