A Short History of Steel and the Bessemer Process

Jul 22, 2018 · Cast iron is strong, but it suffers from brittleness due to its carbon content, making it less than ideal for working and shaping. As metallurgists became aware that the high carbon content in iron was central to the problem of brittleness, they experimented with new methods for reducing the carbon content in order to make iron more workable.diergetos339.jpg" />

Iron Mining Process. From blasting to crushing to separation more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces.diergetos98.jpg" />

In this method, surface of iron is covered with layer of more active metal like zinc. This active metal loses electrons (undergoes oxidation) in preference to iron and hence, prevents the rusting of iron. Zinc metal is generally used for protecting iron and the process is called galvanization.
