Central South University Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: New ultra-lightweight sludge-red mud ceramics (ULS-RMC) were prepared by red mud (RM), clay and dried......
ARTICLE J. Cent. South Univ. (2019) 26: 458-466 DOI: https://doi.org/10.1007/s11771-019-4018-6 Recovery of iron and rare earth elements from red mud through an acid leaching-stepwise extraction..., China Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract: A feasible approach to selectively recover iron and rare earth elements (REEs) from red mud......
with Kjeldahl’s microanalysis method. The settling performance achieved at different flocculant dosages was investigated with high goethite-containing red mud slurry of simulated Bayer process synthesized in laboratory. It turns out that the settling performance of high goethite-containing red mud was better with HPAM. The average settling rate of red mud in the first 5 min and the turbidity......
J. Cent. South Univ. Technol. (2008) 15: 808-813 DOI: 10.1007/s11771-008-0149-x Thermal decomposition behaviour of polyacrylamidomethyltrimethyl ammonium chloride in red mud separation process HU... for selecting highly efficient red mud flocculants, the behaviour of polyacryl- amidomethyltrimethyl ammonium chloride (PATAC) in red mud separation process was investigated. PATAC was employed......

with the relative alumina recovery of 98.91%. Processing the resultant red mud can obtain qualified iron concentrate with iron grade of approximate 60% and recovery of about 86% through magnetic separation, resulting in reduction of red mud emission higher than 70%. The results are potential to develop a novel technology for processing high iron diasporic bauxite efficiently and provide references......
