The Bayer Process-The Main Production Method of Alumina

WebBauxite Residue (BR) is the term used to describe the solid residue produced from the alkaline digestion of bauxite in the Bayer Process for the production of aluminum oxide (alumina, Al 2 O 3). BR is produced in large amounts in alumina refineries: about 0.9–1.5 tons of BR per ton of Al 2 O 3 , depending on bauxite quality and plant operating conditions. The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. … See more Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron.
