Bauxite Beneficiation: An Approach to Value Addition in ...
2021-7-2 · Non-metallurgical bauxite ore is generally sold at higher prices, and consequently can offset lower recovery and higher beneficiation costs. The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values.

Beneficiation of Bauxite - eprints@NML
BAUXITE deposits generally occur at or near the surface and are usually covered with shallow layer of overburden. The ore is almost invariably mined by open pit methods. The usual practice is to thoroughly strip and clear the overburden, after which the ore body is blasted to permit excavation by mechanical shovels. Some deposits contain highly siliceous clays and

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.
