Geochemical Characteristics and Toxic Elements inAlumina

Currently, manufacturers often adopt the chemical ore dressing processfor alumina refining. This process uses the alkali method (sodium hydroxide or sodium carbonates) to producealuminafrom bauxite and can be divided into the Bayer process, the sintering method, and the combined method [4,5].The main components of the red mud are hematite (Fe 2 O 3), calcite (CaCO 3), cancrinite (Na 6 …
