    The important feature of the EAF steelmaking process is that the raw materials are recycled steel scrap and fluxes without the step of iron ore extraction. This results in overall cost of per tonne of annual installed capacity in the range of $127–182/t ($140–200/ton) for an EAF-based operation compared to approximately $1110/t ($1000/ton

    Iron Making. The first step to making steel is to make the iron from which it will be made. This is usually done with the help of coal. Raw bits of iron ore, coke, and lime are put into something called a blast furnace. Here, they result in molten iron (which is also called “hot metal. Steelmaking.
