Iron Extraction Process. In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore. The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG.
Wrought iron is composed primarily of elemental iron with small amounts (1–2 percent) of added slag (the byproduct of iron ore smelting, generally consisting of a mixture of silicon, sulfur, phosphorous, and aluminum oxides).
Early manufacture of iron. Iron is an important material in human history. Iron occurs only rarely as an elemental metal and usually requires processing from ore before it can be used.
Iron is an enigma – it rusts easily, yet it is the most important of all metals. 90% of all metal that is refined today is iron. Most is used to manufacture steel, used in civil engineering (reinforced concrete, girders etc) and in manufacturing.
Iron making. Iron ore is mined in around 50 countries – the largest producers are Australia, Brazil and China. Around 98% of iron ore is used in steelmaking. During the ironmaking process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
Steel is iron that has most of the impurities removed. Steel also has a consistent concentration of carbon throughout ( to percent). ... Another way to create steel from pig iron is the Bessemer process, ... One is the huge availability of iron ore. The second is the .

Iron ore is the key component in steel, the most widely used of all metals. In South Africa our iron ore operations are made up of a % shareholding in Kumba Iron Ore Limited (Kumba), a leading supplier of seaborne iron ore. Kumba is listed on the Johannesburg Stock Exchange and operates three mines.
The method does not use water to process iron ore, instead it transforms mining tailings – with low iron content and no commercial value – into high iron content and low contaminants, making ...
Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufacturing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is converted to steel in a basic oxygen furnace (BOF).
