Beneficiation of bauxite

The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.

The removal of the overburden exposes the bauxite DSO ore, which is free-dig in nature meaning no drill or blast is required. Front end loaders will be used to mine the bauxite and load directly into mobile in-pit screens. Screening of the bauxite ore will be to a maximum size of 100mm, resulting in a product suitable for export.

Mining and Refining – Process - World Aluminium

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.

Unlike ores from base metals, the grade of most bauxite found through mining is acceptable. Bauxites of Brazil, South-East Asia, as well as some types found in Australia and China, need up-grading from the crude ore. This is achieved by washing and screening, and then the super-fine fractions (clayey components) are removed.
