| Abstract Scope |
The current study aims at investigating the green enhancement of the solid-state reactions of kaolin-Na2CO3 mixture during the sintering process by the addition of waste materials containing approximately 70% Na2CO3, and waste carbon anodes. The study focuses on optimizing the sintering process to achieve high alumina percent recovery percentages and characterizing the resulting alumina product. Key evaluation parameters include alumina percent recovery, silicon content, and the structural and phase composition of the obtained alumina. It has been noted that the sintering temperature is significantly reduced from the conventional 1360°C to an environmentally and economically favorable 800°C. Overall, this study demonstrates the feasibility of utilizing waste materials for aluminium industry, showcasing not only environmental advantages but also economic benefits through the efficient use of resources. Further research is warranted to fully explore the potential applications of the recovered alumina and to refine the process for large-scale implementation. |
