Creating Steel HowStuffWorks

Impurities, including carbon, are oxidized and float out of the iron into the slag. When the carbon content is right, you have carbon steel. Another way to create steel from pig iron is the Bessemer process , which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter .

Jul 19, 2011Impurities in Pig Iron and Their Effects 1. Phosphorous. The source of this impurity in iron is from the ore. Manganese dioxide in ore is reduced at higher temperature as the reduction reaction is endothermic in nature. Manganese thus formed gets mixed up with iron. Some of the manganese is removed by acid slag.

Iron in the Industrial Revolution ThoughtCo

While Britain had good iron ore reserves, the iron produced was of a low quality with plenty of impurities, limiting its use. There was plenty of demand, but not much was produced as wrought iron, which had many of the impurities hammered out, took a long time to make, and was available in cheaper imports from Scandinavia.

separators grab the iron and discard the silica and sand. Thus, the ore is "concentrated" by removing the waste materials. The concentrate from the separators is pumped to fine screening. The oversize material is returned to the balls mills, while the undersize (with the most impurities removed) becomes the final concentrate. Waste

How Is Iron Extracted From the Earth? Reference

Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.

Iron ore

Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.

IMPURITIES IN IRON ORESIRON ORE FORMATIONORIGIN OF IRON ORE BODIESMAGNETITELIMONITESIDERITEThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so called BessemerRead More
