Iron and steel industry in the United States - Wikipedia

The traditional large integrated steel mill, which reduces metallic iron from ore (iron oxide) and makes it into pig iron and steel, has been steadily declining in importance for decades in the US. The second type, the mini-mill, or specialty steel mill, which produces new steel products by melting steel scrap, now produces the majority of steel in the US.

Direct-Reduced Iron - an overview | ScienceDirect Topics

Because of the separation of iron reduction and iron melting/coal gasifying in two steps, a high degree of flexibility is achieved and a wide variety of coals can be used. The process is designed to perform at elevated pressure, up to 5 bar. Charging of coal and iron ore is performed through a lock hopper system. The reducing gas contains 65–70% CO, 20–25% H

Steelmaking - Wikipedia

Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladles.
