Steelmaking and Refining Introduction to

Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required.

How Is Magnesium Extracted? Reference

Once the magnesite and ferrosilicon alloy are mixed, they are heated until they vaporize, and the resultant magnesium vapor is collected in cooling vessels to create magnesium. In the third process, which is primarily used in Australia, magnesite ore is dissolved in hydrochloric acid, creating magnesium chloride.
