The Making of Iron & Steel

2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).

An Overview of Steelmaking Process, Global Market Size

Aug 28, 2019 Integrated steelmaking operations fall into three main phases: Reduction: lronmaking. Iron ore is a combination of iron with oxygen and various other unwanted substances known as 'gangue'. The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent.

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.

Major Mines & Projects U.S. Iron Ore Mine

The Mesabi Range contributed 70-75% of the total ore production. In 1965, direct-shipping ore contained 51-61% iron, and pellets produced from quartz-magnetite BIF 60-65% iron. Manganese-rich iron ore (5.6-14.8% Mn) was mined in the Cuyuna Range, contrasting with the low Mn-content of ore in the rest of the district (mostly 1% Mn; Marsden 1968

2 is used to reduce iron ore pellets to "direct reduced iron" (DRI, or sponge iron). The reaction takes place in a shaft furnace, a type of furnace that uses gas reductants to make DRI. The operating temperature can be fairly low, around 800°C. The DRI is then fed into an EAF and turned into steel by further processing it and adding carbon.
