The Extraction of Iron

Cast iron has already been mentioned above This section deals with the types of iron and steel which are produced as a result of the steel-making process Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron Wrought iron is quite soft and easily worked and has little structural strength...

Tempering (metallurgy)

Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloysTempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air The exact temperature determines the amount of hardness ....

What's the process of iron ore mining?

Jan 20, 2017· Mining iron ore begins at ground level Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth Taconite rock comprises about 28 percent iron; the rest is sand or silica These samples are analyzed and ca....

Human iron metabolism

Human iron metabolism is the set of chemical reactions that maintain human homeostasis of iron at the systemic and cellular level Iron is both necessary to the body and potentially toxic Controlling iron levels in the body is a critically important part of many aspects of human health and disease...

Direct reduced iron

Hot-briquetted iron (HBI) is a compacted form of DRI designed for ease of shipping, handling and storage Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy The direct reduction process uses pelletized iron ore or natural "lump" ore...
