11. There are three types of iron powder classifications : reduced iron powder, atomized powder, and electrolyte iron powder. 12. For example, aluminium will reduce iron ( III ) oxide to iron, becoming aluminium oxide in the process: 13. Electric arc furnace steelmaking is the manufacture of steel from scrap or direct reduced iron melted by electric arcs. 14. Treatment techniques which may be successful in removing or reducing iron bacteria include physical removal, pasteurization, and chemical treatment. 15. The output of those plants, which is called direct reduced iron , could be used in the electric furnaces of Trico. 16. Other mills are using more scrap substitutes such as direct reduced iron from iron ore, and pig iron from Brazil. 17. Direct reduction refers to processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. 18. Directly reduced iron is highly susceptible to oxidation and rusting if left unprotected, and is normally quickly processed further to steel. 19. Although reduced iron is copious at the vent surface, it must be in its oxidized form to be coupled to respiration. 20. It also serves to export DRI ( direct reduced iron ) and finished products such as steel bars, rods, and billets.
