The gas-based reduction of ironsands using various reductants—including hydrogen, carbon monoxide, solid carbonaceous agents, and methane—has been extensively studied (Park and Ostrovski in ISIJ Int 43:1316–1325, 2003; Wang and Yuan in Int J Miner Process 81:133–140, 2006; Paunova in Metall Mater Trans B-Proc Metall Mater Proc Sci 33:633–638, 2002; Schwebel et al. in Appl Energy 113:1902–1908, 2014; Longbottom et al. in Metall Mater Trans B-Proc Metall Mater Proc Sci 38:175–184, 2007; Park and Ostrovski in ISIJ Int 44:999–1005, 2004). Across reductant types, a consistent finding is the relatively poor reduction kinetics of ironsands compared to hematite and magnetite.

摘要

The gas-based reduction of ironsands using various reductants—including hydrogen, carbon monoxide, solid carbonaceous agents, and methane—has been extensively studied (Park and Ostrovski in ISIJ Int 43:1316–1325, 2003; Wang and Yuan in Int J Miner Process 81:133–140, 2006; Paunova in Metall Mater Trans B-Proc Metall Mater Proc Sci 33:633–638, 2002; Schwebel et al. in Appl Energy 113:1902–1908, 2014; Longbottom et al. in Metall Mater Trans B-Proc Metall Mater Proc Sci 38:175–184, 2007; Park and Ostrovski in ISIJ Int 44:999–1005, 2004). Across reductant types, a consistent finding is the relatively poor reduction kinetics of ironsands compared to hematite and magnetite.
