Bauxite The Aluminum Association
The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil loed in various tropical and subtropical regions. The ore is acquired through environmentally responsible stripmining operations.

Ore Wikipedia
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore
Aluminum Smelting Furnaces and Processing of Bauxite Ore
The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks
