Metallic mineral resources are minerals from which a metal can be extracted. Bauxite is the primary ore of aluminum, a metal. Its minerals—gibbsite, boehmite, and diaspore—contain aluminum oxide and are mined to produce alumina and then aluminum metal. Because its main value is in yielding a metal, bauxite is classified as a metallic mineral resource. It’s not a noble gas, and it’s not a fossil fuel. It’s not a nonmetallic mineral resource, since its economic purpose is to supply a metal.
