DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

A short description of the sintering process is also presented in Fernández--González et al. (2018). Figure 2.1 shows the main parts of an iron ore sintering plant (Dwight–Lloyd machine). Despite at first instance the agglomeration of ores has imposed as a process required in the iron extractive metallurgy, this process has changed with the
Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.
Beneficiation is a crucial step in the chrome plant process flow, as it involves the separation of chromite from other minerals present in the ore. Various techniques, such as gravity separation, magnetic separation, and flotation, are used to achieve this separation. Gravity separation relies on the difference in density between …
The use of sinter influences hot metal production substantially and significantly affects an integrated steel mill's total emissions. Sintering of iron ores is an enormous energy-intensive and resources consuming process. Introducing a selective waste gas recirculation (SWGR) to the sintering process reduces the energy …
