    The bauxite formed a bed averaging 2 m thick. The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite.Bauxite NETZSCH Grinding & Dispersing,Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. It contains a mixture of oxides like aluminium hydroxides, hydrous aluminium oxides, and minerals like gibbsite, boehmite and diaspore including some clay minerals.
