Size Reduction and Energy Requirement - ScienceDirect

2016-1-1  The average size analysis of an iron ore after preliminary crushing showed a P 80 value of 1173 μm. This was fed to a wet rod mill which produced a product 80% of which passed 150 μm. This was then charged continuously to a ball mill, which was required to produce a product of –34 μm for the purpose of pelletising the ore.

DRI production International Iron Metallics Association

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.

Iron and Steel Technology Roadmap – Analysis - IEA

While iron ore is the source of around 70% of the metallic raw material inputs to steelmaking globally, the rest is supplied in the form of recycled steel scrap. Steel production from scrap requires around one-eighth of the energy of that produced from iron ore – mainly in the form of electricity, rather than coal for production from iron ore.
