Effect of temperature on the dewaterability of hematite ...

One such example is the Bayer process, which is used to produce alumina from bauxite. During the thickening and washing of the process residue (red mud), the operational temperature decreases from around 110 to 35 °C, and thus an understanding of the effects of temperature on suspension dewaterability becomes important.One such example is the Bayer process, which is used to produce alumina from bauxite.
