the process. 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%.

Mining and Refining Process

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.

Bauxite Extraction Process — WORLDEQUITY

Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
