Guinea has become entrenched as a major bauxite exporter to China in recent years. China imported 52.7 Mt of bauxite from Guinea in 2020. This is up 10.9% y/y, and accounts for 47.2% of all of China's bauxite imports. There is precedence for unrest in Guinea to support alumina spot prices and fuel bullish sentiment in the aluminium market.

This paper presents the three-dimensional (3D) data interpretation of a ground-penetrating radar (GPR) survey, in conjunction with the existing boreholes, covering the area of the Az Zabirah bauxite deposits, northern Kingdom of Saudi Arabia. The purpose of this study was to measure and map the volume of the bauxite deposits in the selected survey area, as well as to prove the …

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore.
