Red mud is a kind of industrial solid waste produced in the process of extracting alumina from bauxite. Its main chemical components are SiO 2, Al 2 O 3, CaO, Fe 2 O 3, Na 2 O, and TiO 2.Every one ton of alumina is produced with the discharge of 1.0–1.8 tons of red mud.

Bauxite Mining and Alumina Refining

Washing and beneficiation (further treatment of the ore to concentrate the minerals) if necessary. Delivery to export or to local refineries. Approximately 165 million tonnes of bauxite are mined each year. Bauxite is generally transported to refineries by conveyor, rail, or ship. Some alumina refineries are located close to their bauxite mines.

Mining and Refining – Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.

Environmental Guidelines for Aluminum Manufacturing

In the bauxite mine, where beneficiation and ore washing is practiced, a tailings slurry of 7-9% solids is produced for disposal. The preferred technology is to concentrate these tailings and dispose of them in the mined out area. A concentration of 25-30% can be achieved
