  • 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.


    Ore is valued, primarily containing alumina, and the less silica, the better. To characterize the quality, the so-called silicon modulus of bauxite was introduced, the formula for finding it: μ Si = Al 2 O 3 / SiO 2 The resulting value shows which of the methods is better to process the ore.
