subject to beneficiation, the laboratory preparation will include a screening step as well as additional drying and weighing steps and the calculation of a percentage yield. Although bauxite comprises a mixture of minerals, the industry-standard analytical method for reporting the composition is by elemental analysis, expressed as metal oxides.

high as 10.30%. The beneficiation step also leads to an enrichment of the alumina content in bauxite as the finer fractions contain low alumina. From the above it is evident that the quality of ore can be improved by employment of suitable screening opera-tions for the removal of the lower grade of fines. Interest in the beneficiation of

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.
