In this dissertation, the selective leaching of the chemical elements Scandium, Titanium and Yttrium, which are included in red mud, was investigated. Specifically, red mud is a by-product from aluminium industries. This by-product contains valuable chemical elements, such as Rare Earth Elements (REEs) and others. The extraction of these elements will lead to the usage of them in new applications. Leaching, thermal leaching and hydrothermal processing were studied, for the recovery of these valuable metals. Hydrothermal process has studied for the first time, for the red mud treatment. The results of this method were very encouraging, since the recovery of Sc, Y, Fe and Ti reached 100%, 78.1%, 25% and 25% respectively, for the combination of HCL with HNO3. In conclusion, with the extraction of the chemical elements from secondary resources, the control of the consumption and their balance in the nature will be achieved.
