Physico - Chemical and Morphologic Structural Characterization of the Red Mud Obtained in the Romanian Alumina Plant

Abstract:

The red mud is the main insoluble waste product from the manufacture of alumina by the Bayer hydrometallurgical process. Due to the accumulation in large quantities (0.8-1.2 metric tons waste / 1 metric ton of alumina) with a relatively high content of residual alkali and small granulation, it has been subject to many research activities, especially related to the techniques of neutralizing and enhancing its reuse under the form of various subproducts. This paper presents the results of the work undertaken by the collective of authors to evaluate the physico-chemical and morphological structure of red mud resulting from alumina production. The physico-chemical and morphological structure were analyzed using complex analytical methods (ICP-AES/OES, DCP, AAS, EDS-EDAX, SEM, DTAC, XRF, XRD, optical microscopy). The aim was to identify potentially active compounds for various environmental applications. To estimate the average chemical composition, by element, we used dispersion analysis, through the Gauss normal distribution method.
