It had about 800 members and ...
Iron mining in the United States produced 48 million metric tons of iron ore in 2019. [1] Iron ore was the third-highest-value metal mined in the United States, after gold and copper.

The American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME) is a professional association for mining and metallurgy, with over 145,000 members. [1] The association was founded in 1871 by 22 mining engineers in Wilkes-Barre, Pennsylvania, and was one of the first national engineering societies in the country.
Iron ore, coke, and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled, and marketed as pig iron; the rest flows into basic oxygen furnaces, where it is converted into steel.
Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...
The AIST was formed from a merger from two older organizations, the Association of Iron and Steel Engineers and the Iron and Steel Society in 2004. [4] AIST is a member organization of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME). The head office of the organization is in Warrendale, Pennsylvania.
