  • Energy Use in US Steel Manufacturing - large.stanford.edu

    These reactions are endothermic and require energy input. For example, the reduction of iron ore to iron will require energy beyond simply heating the iron ore to complete. With an understanding of the energy required for each of the major subprocesses in steel production, we can now discuss how much energy is used to create a steel object.

  • How is Steel Produced? | World Coal Association

    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).

  • Can We Make Steel Without Coal? - Coal Action Network Aotearoa

    Steel is made in a subsequent process as an alloy of iron and carbon (along with some other elements). Around 1% of the carbon from the coke remains in the raw iron to provide the source of that carbon. So coal (as coke) is a reducing agent, a source of energy to drive the process and a source of carbon to incorporate in the steel.
