of Science and Technology Beijing摘 要:Large scale utilization is still an urgent problem for waste red mud with a high content of alkaline metal component... separation.Alkaline metal salts were usually added to enhance reduction of laterite ores.The feasibility of co-reduction roasting of a saprolitic laterite ore and red mud was investigated.Results show that the red......
of Advanced Metallurgy, University of Science and Technology Beijing摘 要:Red mud is a bauxite residue generated during the process of alumina production. In this research, the occurrence mode of scandium in the Bayer red mud was investigated mainly by electron probe microanalysis(EPMA). The Bayer red mud used in this work is composed of 21.47 wt%hematite......

Complementation in the composition of steel slag and red mud for preparation of novel ceramicsYan-bing Zong1,Wen-hui Chen1,Yong Fan2,3,Tai-lin Yang1,Zhao-bo Liu1,4,Da-qiang Cang11. School.... The results confirmed that red mud can reduce the volumetric instabilities through the complementarity of red mud and ferroalloy slag. The crystal phases in the ceramics are all pyroxene group minerals......
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......
