1 Introduction 1.1 Overview of Bauxite Ore. As a residue of strong chemical weathering, bauxite is mainly composed of Al-oxyhydroxides, Fe-oxides/-oxyhydroxides and Ti-oxides (mainly TiO 2 phases) (Bárdossy, 1982, 1994; Bárdossy and Aleva, 1990; D'Argenio & Mindszenty, 1995; Retallack, 2010).Bauxite deposits can be classified into …

The deposit was estimated to contain a mineable 1.5 Mt of washed bauxite with an average composition of 49.4% alumina (Wolfenden and Haile, …
Bauxite is an important ore of aluminum, composed mainly of aluminum oxide and hydroxide minerals. It was named after the village Les Baux-de-Provence in southern France, where it was first discovered in 1821 by geologist Henri Rouvère. Bauxites have a range of commercial applications, such as for the production of aluminum metal and …

Bauxite is an aluminium-rich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of non-metallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.

Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in …

Abstract. The term «bauxite» was introduced by Berthier (1821) and refers to rock samples belonging to the laterite type. Lateritic bauxites have been studied by many, mainly by prospection and exploration geologists, and by geologists, soil scientists and geomorphologists interested in the mechanisms of bauxite formation and evolution.
