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.
Because bauxite mines are frequently located in remote and ecologically diverse areas, mining requires access to these sites and the energy infrastructure to support mining operations. Linear infrastructure such as roads, power lines, and rail lines can lead to habitat fragmentation and impacts along their route.
