Étude expérimentale de la production de fer électrolytique en milieu alcalin : mécanisme de réduction des oxydes et développement d'une cellule

Abstract : Iron is one of the few metals which is not industrially produced by electrolysis. The electrowinning of iron metal from its oxides in alkaline solution has been studied to develop such an ironmaking route. Two approaches have been adopted. The first one concerns the evaluation of the reaction mechanism. The study of iron ions electrochemistry in alkaline media shows that the electrodeposition of iron metal is possible. The study of a single iron oxide particle reduction reveals that a reaction of the hematite solid phase is possible. The analysis of a partially converted particle proves that magnetite is formed as an intermediate. The second field of study is dedicated to the production of iron metal in various electrochemical cells, using a suspension electrolysis process. The influence of the key operating parameters is established to assess the possible scale-up. All these elements are gathered to propose the main features of an industrial cell dedicated to the reaction
