Sep 09, 2019 · In 1889, Austrian chemist Carl Joseph Bayer discovered a method of purifying bauxite (aluminium’s most common ore) to yield alumina. The Bayer and Hall-Héroult processes remain the basis of aluminium production to this day. As for the name, ‘aluminium’ was adopted in the early 19th century because the -ium suffix sounded ‘classical’
