Get MoreWrought iron is commercially purified iron. In the Aston process, pig iron is refined in a Bessemer converter and then poured into molten iron silicate slag. The resulting semisolid mass is passed between rollers that squeeze out most of the slag.
Get Morerefinery conditions. The iron oxides essentially pass through the refinery process unchanged. They either remain insoluble or react and reprecipitate and end up in the red mud. However, very low levels of iron in bauxite often result in a high concentration of iron in the liquor and consequently leads to a high iron content in the precipitated

Get MoreThe three-layer process for aluminum refining was developed by Hoopes of the Aluminum Company of America (Alcoa) in the early 1900s. The anode consists of impure aluminum alloyed with 25% copper to give a density of 2.8 g cm −3 at 1000 °C. The electrolyte typically consists of a cryolite–BaF 2 molten mixture (sometimes containing barium chloride (BaCl 2) or calcium …

Get MoreThe pig iron can be further refined to produce steel or wrought iron. Both these methods reduce the carbon content of the pig iron, which in turn reduces the brittleness property of the metals. Wrought Iron Process. Wrought iron is produced by pummeling the pig iron using mechanically driven hammers in a wrought iron works.
Get MoreTo improve the quality of the iron, it needs to be refined by lowering the amount of carbon. This is done by melting the metal and reacting the carbon with pure oxygen to form carbon dioxide gas. In this way the carbon is burned off and the quality of the iron improves. The iron can now be used in the steel-making process.
