Conceptual design and cost analysis of a large‐scale plant for converting red mud into building materials

Abstract The high level of sodium in red mud (RM) is one of the main issues hindering its incorporation as a raw material for construction and building materials. This paper presents a few studies on building materials developed using more than 70% w/w RM content. A proposed industrial process flowc...
