Iron cycling at corroding carbon steel surfaces
Surfaces of carbon steel (CS) exposed to mixed cultures of iron-oxidizing bacteria (FeOB) and dissimilatory iron-reducing bacteria (FeRB) in seawater media under aerobic conditions were rougher than surfaces of CS exposed to pure cultures of either type of microorganism. The roughened surface, demonstrated by profilometry, is an indication of loss of metal from the surface. In the presence of C...
متن کاملCenter for Advanced Sustainable Iron & Steel Making
Current blast furnace technology is a two-stage ironmaking process that requires that iron ore concentrate first be formed into pellets, fired at 1260°C, cooled, transported to the blast furnace, and then re-heated to approximately 1500°C to produce pig iron. This heating, cooling, and then reheating wastes a great deal of energy, which would be saved if the ironmaking process had only a single...
متن کاملScrap Iron and Steel Recycling in Nigeria
Nigeria is blessed with abundant iron ore deposits of nearly 3 billion tonnes and other basic minerals for steel production including coal and limestone. Yet the Nigerian steel sector has collapsed principally due to shortage of raw materials particularly iron ore for the integrated steel plants and billets for the rolling mills. The privatization of the steel sector that was done in 2004-2005 ...
متن کاملLife cycle assessment of steel production from iron scrap: a case study at a steel plant
Background and Objective: The steel industry is the world's largest consumer of energy. A large amount of iron waste is produced annually, which its use in the steel industry can be economic. The purpose of this study was to investigate the environmental impacts of the steelmaking from iron scrap as a raw material using a life cycle assessment (LCA) method. Materials and Methods: Simapro softw...
