Reduction behavior of iron in the red mud

Red mud or bauxite residue contains significant quantities of industrial metals such as Fe, Al, and Ti, well rare earth elements Sc, Ce, La. The authors performed a laboratory-scale project dealing with stepwise recovery valuable from two residues, namely Iranian red (IRM) Turkish (TRM). first stage involved the iron which was present in large mud. Two different methods were investigated for this purpose: 1) solid state reduction followed by wet magnetic separation 2) smelting. In scope paper, some results pyrometallurgical part are presented. According to solid-state experiments, it found that more excess coal needed IRM (35%) than TRM (15%) maximize reduction. Temperature had effect on process metallization increased about 70% 95% when temperature raised 1000 1200?C. Metallization degree reported be slightly higher (96.2%) (94.1%). demonstrated high can achieved regardless chemical mineralogical composition sample.
