Iron processing | Britannica
Throughout the 20th century, many new iron-making processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged. Direct reduction, in which iron ores are reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico …
Iron processing - Iron making | Britannica
Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from stone combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making …
Human iron metabolism - Wikipedia
06.12.2005 · Human cells require iron in order to obtain energy as ATP from a multi-step process known as cellular respiration, more specifically from oxidative phosphorylation at the mitochondrial cristae.Iron is present in the iron-sulfur clusters and heme groups of the electron transport chain proteins that generate a proton gradient that allows ATP synthase to synthesize ATP (chemiosmosis).

How Is Cast Iron Made? | Sciencing
Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds (sand) or non …

Regulation of cellular iron metabolism
15.03.2011 · The ferroportin-mediated efflux of Fe 2+ from enterocytes and macrophages into the plasma is critical for systemic iron homoeostasis. This process is negatively regulated by hepcidin, a liver-derived peptide hormone that binds to ferroportin and promotes its phosphorylation, internalization and lysosomal degradation [6,12]. Hepcidin is primarily expressed in hepatocytes as a precursor pro-peptide. Pro-hepcidin undergoes proteolytic processing …
STATE OF THE DIRECT REDUCTION AND REDUCTION SMELTING …
The processes that produce iron by reduction of iron ore below the melting point of the iron produced are generally classified as direct reduction processes, and the product is referred to as direct reduced iron. The processes that produce molten metal, similar to blast furnace liquid metal, directly from ore are referred to as direct smelting processes. In some of the processes the objective ...
s-process - Wikipedia
The slow neutron-capture process, or s-process, is a series of reactions in nuclear astrophysics that occur in stars, particularly AGB stars.The s-process is responsible for the creation (nucleosynthesis) of approximately half the atomic nuclei heavier than iron.. In the s-process, a seed nucleus undergoes neutron capture to form an isotope with one higher atomic mass.
