Bauxite Ore Extraction Process - Grinder Process
Bauxite Ore Extraction Process. Unlike other base metal ores, bauxite ore does not require complex extraction processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay. In many cases, bauxite ore extraction process can be accomplished by some combination of washing, wet …
Mining and Refining – Process - World Aluminium
Mining and Refining – Process Aluminium is the most abundant metal in the earth’s crust. The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.

Bauxite is collected from the ground in an open-pit mining operation. It doesn’t sit very deeply in the earth’s crust, so some energy can be saved on drilling. However, to recover all the aluminum in an area, swaths of land must be bull-dozed to reveal the dirt and ore underneath. Once collected, the bauxite ore has to be refined.
