Carbothermic Reduction of Bauxite Residue.

Shigen-to-Sozai, 1999
A recovery method of iron component as metallic phase from bauxite residue (red mud) discharged from Bayer process was examined. Tablets prepared with fine mixtures of red mud and carbonaceous materials were heated up to various temperatures to reduce iron oxides in the red mud.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
