Picture 1: Mineral processing in ancient times [4], [5] 4 Bauxite Beneficiation The idea of bauxite beneficiation is neither new nor out of fashion. In the ”Alumina Technology Roadmap” developed at a workshop in Fremantle, WA in May 2001, following statements were enunciated: Impurity Removal: Bauxite and Bauxite Beneficiation Efficient use of the world´s bauxite resources requires

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to

Biogenesis thus plays a significant role in bauxite mineralization. Various types of bacteria and fungi, such as Bacillus polymyxa, Bacillus coagulans and Aspergillus niger, were found to be efficient in significant calcium solubilization and partial iron removal from bauxite ore. Probable mechanisms in the biobeneficiation process are analyzed.
