Jan 15, 2021· Bauxite is the main raw material in primary aluminum production and its reactive silica content and mass ratio of Al 2 O 3 to SiO 2 (A/S) has a critical role in the economic viability of Bayer process. As a major source of the reactive silica, clay impurities should be removed from the ore as much as possible by a beneficiation method such as froth flotation before the Bayer processing.
Bauxite Beneficiation Electrostatic Aluminum is the most common metal element found on Earth, totaling about 8% of the Earth's crust. However, aluminum as an element is reactive and therefore does not occur naturally – it needs to be refined to produce aluminum metal.
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.
