ENERGY USE IN THE STEEL INDUSTRY Most steel products remain in use for decades or even centuries before their function is no longer needed and they can then be reused remanufactured or recycled. Therefore there is not enough recycled steel to meet growing demand. Demand is met through a combined use of the BF-BOF and EAF production routes.

Ore is stockpiled (1) at the processing plant and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3) the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

Get PriceIron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore leaving behind a soft malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

The EAFs melt scrap metal in the presence of electric energy and oxygen. The process does not require the three step refinement as needed to produce steel from ore. Production of steel from scrap can also be economical on a much smaller scale. Frequently mills producing steel with EAF technology are called mini-mills.
