[0002] Red mud pellets are a type of pellet made from red mud and can be used as a resource recycling product. Their physical and chemical properties are affected by the properties of the red mud itself and the processing technology.

[0003] Today's red mud is an industrial solid waste discharged when the aluminum industry extracts alumina. It is rich in various elements, among which iron is one of the important elements that can be recycled.
