Polonium has a position in the periodic table that could make it a metal, a metalloid or a nonmetal. It is classed as a metal as its electrical conductivity decreases as its temperature rises. Because of this property it is used in industry to eliminate dangerous static electricity in making paper or sheet metal.

Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …

Metals, Nonmetals, and Metalloids are three classes of elements. The majority of elements in the periodic table are metals which are characterized by being shiny and solid (except Mercury) yet still malleable (or able to be molded and shaped). Metals are excellent conductors of electricity and heat. Nonmetals are primarily listed on the right side of the …
Details
Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.
Details
Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world's bauxite production is refined through the Bayer chemical …

Bauxite is the world's main source of aluminium, ... More than 85% of the bauxite mined globally is converted to alumina for the production of aluminium metal. An additional 10% goes to non-metal uses in various forms of specialty alumina, while the remainder is used for non-metallurgical bauxite applications. ...
Details
Non-metal properties have a relatively low boiling point, and other non-metals are gases. Likewise, non-metals are poor heat conductors, and solid non-metals are dull and brittle. Many non-metals are strongly reactive, while others are in no way reactive. It depends on the number of electrons in the outer amount of energy.
