Bauxite Is How Discovered

March 23, 1821: Bauxite Discovered EARTH Magazine

The discovery of bauxite occurred near Les Baux, France, an ancient village near the Mediterranean Sea named for, and carved from, a rocky outcrop On March 23, 1821, a geologist named Pierre Berthier discovered a reddish, claylike material He found that the substance, later named bauxite after the village, consisted of about 50 percentAt present, bauxite is so plentiful that only deposits containing a content of aluminium oxides greater than 45% are selected to manufacture aluminium Bauxite derives its name from a small French town called Les Baux, where bauxite was first discovered in 1821Bauxite an overview | ScienceDirect TopicsBauxite Resources sold its interest in Aurora to Yankuang in 2016 Juturna: This deposit is located 65 km east of Perth and approximately 20 km southwest of Northam in the Bakers Hill region of the Darling Range Bauxite mineralisation occurs in three main, flatlying pods that range in thickness from 02 m to 112 mBauxite | Geoscience Australia
