Bauxite tailings are a major type of solid wastes generated in the flotation process. Based on the high Fe 2 O 3 content and low Al 2 O 3 content of bauxite tailings, ferric-rich ceramics were prepared in this study. It has been found that the sintering temperature of the ferric-rich ceramics is only about 1100 °C.
