“…At present, the main applications of red mud in the field of building materials are the preparation of bricks, cement, glass ceramics, etc. [39,40]. The specific process of using red mud to prepare bricks is to mix red mud, shale, and slag evenly in proportion; then cut into blanks; then bake through drying, preheating, and "low-temperature slow-burning" technology; and finally, heat preservation and cooling.…”

Red mud is a highly alkaline solid waste discharged in the alumina production process. Because of its large amount of discharge and high alkalinity, it is mostly stored in dams, occupying a large number of land resources and posing a great safety hazard to the ecological environment. The large-scale consumption of red mud is a global technical problem. Different alumina production processes will produce different types of red mud, mainly Bayer process red mud. In addition to its overall utilization in the field of building materials, agriculture, the environment, and the chemical industry, red mud also contains valuable metal elements, such as titanium, iron, scandium, and aluminum, and is an important secondary mineral resource. This paper focuses on the principle and characteristics of red mud metallurgical treatment for the extraction of valuable components and looks forward to the prospect of large-scale, harmless, and high-value comprehensive utilization technology for red mud in China.

“…Wang and his team highlighted that sometimes alkalinity avoids the large-scale utilisation of red mud in cement production. However, calcification-carbonisation red mud is efficient to produce a suitable cement clinker, as their chemical composition is similar [130,131]. Some papers found that the Portland cement hydration is encouraged by a highly alkaline environment in which red mud is distinguished for [132].…”

About 120 million tons of red mud is produced worldwide each year. Due to its high basicity and potential leaching, its storage is a critical environmental problem. This material is typically stored in dams, which demands prior care of the disposal area and includes monitoring and maintenance throughout its useful life. Consequently, it is crucial to figure out an industrial solution able to consumes large volumes of this material. At this moment, there are several studies, the majority in metallurgical procedures, building materials, and in the chemical industry, discussing how to reuse red mud. This paper provides a review of the aluminium process, including metal importance, its global production, and the environmental impact due to its manufacture process. It presents a review of the potential application of red mud showing its overall generation, some relevant characterisation results collected from the literature, and its utilisation in diverse areas of engineering. The study aimed to highlight applications where red mud characteristics may be favourable.
