May 08, 2014 · BAUXITE MINING PROCESS AND ASSOCIATED OCCUPATIONAL HEALTH HAZARDS AND RISKS. Although a very small percentage (less than 1% globally) of aluminum is derived from ores such as nepheline and from alternative sources, such as fly ash from coalfired power stations, bauxite mining represents, by far, the most common initial upstream step in the eventual production of aluminum

Mining and Refining – Process World Aluminium
The aluminiumcontaining 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 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.
