Chapter 13 ~ Non-Renewable Resources - Environmental Science

Also note the large increase in production of most metals since 1977. Iron and aluminum are the metals produced and used in the largest quantities. The life index (or production life, calculated as the known reserves divided by the annual rate of production) of aluminum is about 592 years, and for iron ore it is 58 years (Table 13.1).

Puddling (metallurgy) - Wikipedia

Modern puddling was one of several processes developed in the second half of the 18th century in Great Britain for producing bar iron from pig iron without the use of charcoal. It gradually replaced the earlier charcoal-fueled process, conducted in a finery forge . The need for puddling [ edit] Pig iron contains much free carbon and is brittle.

Metallurgist | Article about metallurgist by The Free Dictionary

The gases formed (carbon monoxide) reduced the iron oxides. The relatively low temperature of the process and the large quantity of iron slag impeded carburization of the metal and permitted only the production of iron with a low carbon content. The process had low productivity and provided extraction of only about half of the iron in the ore.

Bloomery - Wikipedia

The temperature and ratio of charcoal to iron ore must be carefully controlled to keep the iron from absorbing too much carbon and thus becoming unforgeable. Cast iron occurs when the iron absorbs 2% to 4% carbon. Because the bloomery is self- fluxing, the addition of limestone is not required to form a slag.

Cast Iron: Properties, Processing and Applications - Matmatch

Cast iron is an iron alloy containing 2 wt.% - 4 wt.% carbon, 1 wt.% - 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

Infographic: the Iron and Steel Manufacturing Process - Analyzing Metals

Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.
