Influence of FeO and sulfur on solid state reaction between MnO-SiO2-FeO oxides and an Fe-Mn-Si solid alloy during heat treatment at 1473 KCheng-song Liu1,Shu-feng Yang1,Kyung-ho Kim2,Jing-she..., Tohoku University摘 要:To clarify the influence of Fe O and sulfur on solid state reaction between an Fe-Mn-Si alloy and Mn O-Si O2-Fe O oxides under......
. Additionally, there were some transitive valence S-containing ions in electrolyte after the electrolysis, such as , . However, most of the sulfur in bauxite was eventually oxidized into into the electrolyte, and these S-containing ions did not affect the recycling utilization for electrolyte. Key words: high sulfur bauxite; electrolysis; desulfurization; electrolyte; recycling 1 Introduction......
