“…With increasingly stringent environmental protection policies, how to dispose of red mud and bauxite tailings at low cost has become one of the problems that restrict the sustainable development of the aluminum industry. A lot of research has been conducted on red mud and bauxite tailings, which are mainly used for the production of construction materials [3][4][5] , filling materials [6,7] , refractory materials [8] , functional materials [9][10][11] , etc. However, there are still problems such as low value-added products or high process energy consumption or limited solid waste consumption, resulting that most of produced red mud and bauxite flotation tailings are stored in landfills [12] .…”

Polymeric aluminum ferric sulphate(PAFS) was prepared from high-sulfur bauxite flotation tailings and red mud by roasting, acid leaching and polymerization. The effects of leaching temperature, leaching time, liquid-solid ratio on the leaching rate of Al3+ and Fe3+were investigated. The optimal leaching conditions are as follows: leaching temperature 100℃, leaching time 90 min, sulfuric acid concentration 4.5mol/L and liquid-solid ratio 5 mg/L. Infrared spectroscopy and X-ray diffraction analysis was carried out on the PAFS prepared under the optimum process parameters. The characterization of PAFS shows that the synthesized PAFS had polymeric aluminum, iron and hydroxyl structures. Wastewater disposal test of synthetic PAFS shows that the removal rates of COD, turbidity and chromaticity are 45.61%, 75% and 94.18%, respectively.

Red Mud from the Aluminium Industry: Production, Characteristics, and Alternative Applications in Construction Materials—A Review

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.

The aluminum industry generates a significant amount of red mud as solid waste. This waste is high in mineral content, particularly metal oxides, and difficult to treat, manage, and recycle, resulting in malignant environmental effects. A simple, scalable, and precisely controlled hydrochloric acid treatment transforms the red mud into a useful product by selectively removing electrochemically inactive phases. This process produces a highly porous material with a significantly increased surface area, which effectively serves as the cathode material in an aqueous zinc ion battery (AZIB). RM‐HCl, which was treated with acid, had better electrochemical performance than plain red mud (RM). It had an initial specific discharge capacity of 105 mAh g‐1 at 0.2 to 1.8 voltage and a current density of 100 mA g‐1, which stayed at 63% after 250 cycles. It also showed long‐term cyclic stability at high currents of 500 mAg‐1 and 1000 mAg‐1 for 1000 cycles. The properties of a cathode material made from RM have the potential to be a cost‐effective and environmentally friendly option. This study proposes a practical, sustainable, and expandable technique for recycling RM that promotes eco‐friendly and sustainable growth in the aluminium industry.
