Extraction of Aluminium (Aluminium Ore) To generate aluminium oxide from aluminium ore called bauxite is purified, a white powder form which aluminium can be extracted. Occurrence and uses of Aluminium. Hallheroult process for the production of aluminium.
· Mining Immediately prior to mining any deposit, the land is cleared and the top soil, to a minimum of 6 inches, removed and stockpiled for later replacement when mining is completed. The surface occurrence of the ore (usually less than 100 feet) makes the deposits suitable for mining by simple opencast methods.
