 — Adapted from Cuccia, et. el (2001) (pdf) (93.21 K) Waste Generation, Disposal and Reuse. Bauxite is used to produce alumina, which is then used to produce aluminum. Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process.

Bauxite Ore Alumina Product Bauxite is the most widely distributed ore used for alumina production. It is named after the small town in southern France called Les Baux, where it was first mined. Bauxite is typically a mixture of hydroxides of aluminium with iron oxides, silica and aluminosilicates.

The discovery came at a opportune time. The world was embroiled in World War II, pushing up the demand for aluminium. Until then, little attention was paid to finding new sources of bauxite/alumina outside of Europe but the requirement to build planes and other equipment made from aluminum drove the need for new sources.

Fig. 1. Districts of coastal- and plateau-type deposits of bauxite in Suriname. Onverdacht bauxite deposit. Suriname was one of the leading bauxite-producing countries in the world during the Second World War (1939–1945), which generated a boost in bauxite exploration and research on the local deposits. In 1941, the SBM opened the Paranam ...
