Red Mud an overview ScienceDirect Topics

Red mud is composed of minerals such as hematite, gibbsite, calcite, quartz, goethite, diaspore, rutile, kaolinite, etc. ( Wang and Liu, 2012) measured by using X-ray diffractometer. The specific gravity of red mud is 2.77 gcm −3 measured by gas picnometer.

Characteristics Red Mud Project

2005. 5. 2. Red Mud is produced during the Bayer process for alumina production. It is the insoluble product after bauxite digestion with sodium hydroxide at elevated temperature and pressure. It is a mixture of compounds originally present in the parent mineral, bauxite, and of compounds formed or introduced during the Bayer cycle.

Mineral Phase and Physical Properties of Red Mud Calcined

Red mud is a reddish brown coloured solid waste produced during the physical and chemical processing of bauxite. Bauxite is composed of aluminum hydroxide minerals, including primarily gibbsite (Al (OH) 3), boehmite (γ -AlO (OH)), diaspore (α -AlO (OH)), hematite (Fe 2 O 3) and goethite (FeO (OH)) [ 1

Analysis on Physical and Mechanical Properties of Red Mud

Red mud is the tailings generated from the production process of alumina in aluminum industry. With rapid growth of aluminum output in recent years, the discharge amount of red mud increases accordingly. About 120,000,000 t red mud would be discharged globally every year [ 1 ].
