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 products such as abrasives, chemicals, proppants, and more.
