Ore quality can be improved relatively easily and cost effectively by removing clay, known as beneficiation which includes washing, wet screening and mechanical or manual sorting.

A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20.

Imported bauxite demand is expected to grow strongly due to increased Chinese requirements and, in the longer term, because of declining domestic ore reserves and ore quality. Meanwhile, exports from Indonesia have been disrupted by a push to convert bauxite to alumina locally, while Malaysian supply has been restricted by environmental issues.

AGB2A, a Guinea based company, produces one of the best metallurgical grade bauxite for alumina refinery by dry beneficiation process involving crushing and screening of ore. GBT bauxite is unique and different from usual Guinea bauxite as these are embedded in the silica rich fines at the periphery of hillocks.
The bauxite mining industry is booming in Guinea on the back of demand of Chinese, Russian, Gulf and Indian alumina refineries. The bauxite export from Guinea may exceed to over 110 million tons in 2021. Guinea bauxite is the most preferred ore for alumina refineries worldwide thanks to its low reactive silica content and high gibbsitic alumina.
Except Guinea and Indian bauxite, most of the raw ore requires wet beneficiation process mainly to reduce the silica content. The large captive bauxite mines of Darling Range on the western part of Australia are comparatively poor grade and suitable for pit head processing. However, recently ALCOA has stated exporting this bauxite to China.
