##tihuan2##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.
