Aluminum metal has been used in the propellant, explosive and pyrotechnic (PEP) industries for slightly more than 100 years3. Prior to discovery of the Hall Heroult electrolytic process for reducing aluminum from bauxite ore in 1886, the cost of aluminum per kilogram exceeded that of most precious metals.

Bauxite is a sedimentary rock with a high aluminum content. Aluminum, in its various forms and products, is the final stage in a highly energy intensive, greenhouse gas emitting, environmentally harmful industrial process that begins with the mining of bauxite, the principal ore of aluminum.

Aluminum can either be produced from bauxite ore or from aluminum scrap. Refinement of aluminum ore is sufficiently expensive that the secondary production industry commands much of the market. About 40% of aluminum in the US is recovered for secondary refining (USEPA, 1995). Due to high energy requirements, the major primary aluminum producers tend to locate in areas with low energy costs

Red mud, also known as bauxite residue, is an industrial waste generated during the refinement of bauxite into alumina using the Bayer is composed of various oxide compounds, including the iron oxides which give its red color. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to tonnes of red mud are also

Handling of bauxite Loading, discharging environmental impacts Bauxite is one of the world''s most abundant minerals and is stripmined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains ironbearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove.

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminiumcontaining components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.

Bauxite deposits are found across much of western and central Guinea, having been formed by the tropical weathering of underlying, aluminiumrich rocks. The deposits are typically close to the surface. Proven reserves total some 2,300Mt with additional probable reserves of 18,600Mt, most of which contains between 40% and 50% aluminium oxide (Al2O3).

Bauxite refineries produce alumina (aluminum oxide), which is used to create aluminum metal. Bauxite is also used to manufacture other industrial products, such as abrasives, cement and chemicals. There are two operating bauxite refineries in the United States, both of which are located in Louisiana.

The urgency of the search for bauxite in Jamaica was triggered by German Uboats successfully targeting and sinking the ships carrying bauxite from the Guianas to North America for smelting into aluminum. Jamaica was the attractive alternative to the Guianas by being geographically near to North America, with abundant bauxite close to the surface thus easy to extract, and a British colony
