Bauxite is the major ore of aluminum, coming from Australia’s largest bauxite deposit, Weipa in Queensland. Decent specimens of bauxite , are not often seen in mineral collections, surprisingly considering it is so important economically and physically. To quote Wikipedia “Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world’s main source of aluminium”.
