Carbothermic Reduction of Bauxite Residue.

open access: yesShigen-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.

The Detrital Versus Authigenic Origin and Provenance of Mineral Particles in Mesozoic Carbonates of Central Croatian Karst Area

open access: yesGeologia Croatica, 2010
In 1911, Tucan studied the insoluble residue of limestones and dolomites from the Croatian karst realm, and compared it to the composition of terra rossa and bauxite. He concluded that the insoluble residue represented the source material for terra rossa
