Étude du comportement hydrodynamique de suspensions concentrées de particules d’hématite : sédimentation, comportement rhéologique et écoulement forcé dans une cellule inclinée

Abstract : This thesis aims to develop scientific and technological knowledge needed to design a pilot production of steel by electrochemical reduction of hematite particles suspended in an alkaline medium at 110°C in order to provide a reliable and environmentally friendly industrial process, as an alternative to the conventional process based on coal. The mixture considered contains a suspension of hematite of 12% by volume in an aqueous sodium hydroxide solution of 50% by weight. This thesis seeks to study the sedimentation and rheology of hematite suspensions and the hydrodynamic behavior of hematite particles in inclined cell and to quantify the possible phenomeno impact on the cathode
