ALUMINUM INDUSTRY WASTE: COMPOSITION, DIRECTIONS OF USE
Relevance and purpose of the work. In the economy of the future, a significant place will be given to the processing of various industrial wastes, among which, within the Ural region, the most significant volume is occupied by technogenic formations of the mining industry and the production of metals. One of the leading industries within the region is aluminum. Consideration of the material composition and further use is the subject of this work The purpose of the work is to characterize the material composition of technogenic formations of the aluminum industry and show the main directions of processing. Research methodology. The analysis of the available data on the material composition of the initial mineral raw materials - bauxites and technogenic mineral formations - wastes of the aluminum industry was carried out. To study red mud, modern analytical methods were used: X-ray phase analysis on a SHIMADZU XRD-7000 instrument, energy dispersive X-ray spectrometry on an X-MAX instrument and particle morphology studies on a PHILIPS XL-30 electron microscope, X-ray fluorescence analysis on a Hitachi X-MET 8000 instrument. Work results. The material (chemical and mineral composition of technogenic -mineral formations) composition was studied, their specialization for rare metals was shown. Possible technologies for their processing as complex mineral raw materials are considered. Conclusions. The obtained results of the study of the material composition significantly refined both the morphology of the particles and the concentration of a number of impurity elements, allowing to some extent to correct the proposed technologies for their processing.
