Bayer Process an overview ScienceDirect Topics

During the Bayer's process, bauxite is fine milled. As a consequence, the red mud generated has a very fine particle size distribution. The particle size analysis of red mud was carried out using a laser particle size analyzer (MASTERSIZER S, Malvern, UK). Figure 14.2 shows the particle size distribution of red mud received from ALCOA
