Bayer process - Wikipedia

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. The aluminium oxide must be purified before it can be refined to aluminium metal. The Transformation of Bauxite to Aluminum (and the,,Before it can become aluminum, however, bauxite destined for use as aluminum must first be processed into alumina. In 2015, the US Geological Survey estimated that over 95% of bauxite was converted to alumina, with the remainder going toward a variety of productsAlumina Refinery - Outotec,Bauxite and Alumina processing; Alumina Refinery; Outotec® Alumina Refinery.
