Utilization of Red Mud (Bauxite Residue) in Environmental and Geotechnical Engineering Applications—An Overview
https://orcid.org/http://orcid.org/0000-0002-1302-1017
Red mud is also known as bauxite residue, an industrial by-product obtained during the processing of bauxite into alumina. The produced red mud is usually disposed of on land and water bodies, leading to various environmental issues. Red mud is composed of fine particles, various chemical constituents and minerals. It cannot be utilized mainly due to its high alkalinity and the possible presence of heavy metals. Moreover, low hydraulic conductivity, extreme corrosive in nature, high water holding capacity, low shear strength, longer consolidation time, high salinity, lack of plant nutrients, and very low organic content are the other major concerns with red mud. Hence, red mud is to be utilized as an amendment or adsorbent in various engineering applications. There is a serious emergency and a lot of scope to study various physiochemical, mineralogical, and geoenvironmental properties to pave a path to utilize red mud in various applications such as treatment of wastewater, acid mines, reducing swelling of soils and as an amendment for clay liner preparation. This paper aims to review and highlight the applications of red mud as an amendment, adsorbent, catalyst, and coagulant to remove pollutants/contaminants in soil or water.
