Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron is converted into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into steel. The process is known as basic due to the chemical nature of the refractories—calcium oxide and magnesium oxide—that line the vessel to withstand the high

Magnesium is found in seawater and brines, as well as in deposits in the earth. Magnesium reserves are highly concentrated in three countries: Russia, China and Korea. In 2013, identified world resources of magnesite totaled 12 billion tones and world reserves of magnesite totaled 2.4 billion tones with China accounting for 21% (500 million tonnes).

(a) Concentration of the ore. The ore is mined, crushed, ball-milled and then concentrated by froth flotation. This removes unwanted components, including the lead compounds and waste rock. (b) Roasting of the ore in air. The ore roasting usually takes place in a fluidised bed furnace at around 1300 K, with air being blown in at the bottom.

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.

The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
