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

Bauxite Mining The Australian Aluminium Council

Depending on the depth of the caprock, it can be broken by blasting, or simply removed with scrapers and excavators. The bauxite is then mined using excavators or loaders to load the bauxite onto haul trucks and transported to the crusher. Several pits are usually mined simultaneously in order to produce a consistent grade of ore.
