generation of a byproduct, red-mud consisting of undis-solved solids composed of iron oxides, sodium alumino silicates, titania, silica and rare earth elements. The accumulation of red-mud (or bauxite residue) in the world is 30 billion metric tons produced at a rate of 125 million tons per annum (2013). Utilization of red-mud for
Bauxite dissolves and forms sodium meta aluminate because of the amphoteric nature of aluminium, leaving behind insoluble impurities called red mud. Red mud consists of ferric oxide, sand, etc. which are removed by filtration. (b) Aluminium oxide due to its great affinity for oxygen is a very stable compound. It is not reduced easily by common ...
Red mud is an environmental burden during the alumina production process. To mitigate the hazards associated with red mud storage, this study investigated the utilization of alkaline red mud as a treatment agent for acidic mine drainage (AMD) with high concentrations of Fe(II) and Mn(II). This study explored the influence of reaction …
In this study, the statistical optimization of the leaching parameters of aluminum hydroxide extraction from bauxite waste (red mud) was investigated. The extraction parameters were solid-to-liquid ratio, base concentration, reaction temperature, leaching time, and stirring speed.

The LOI of the red mud feed is 9.3%, which is in close approximation with the total loss of bounded and free water content. The TG plot of the red mud-carbon mixture showed an additional decomposition stage in the range of 400–600 °C, with a weight loss of ~8% corresponding to the hematite reduction to magnetite.
