This high-specific-gravity mineral is the most widely used weight barite,

isomorphous with hollandite in practical terms used to deoxidize copper and to absorb trace gases in vacuum tubes blue Mine Run 66-90Barium (IPA: /ˈbɛːriəm/) is a chemical element in the periodic table that has the symbol Ba and atomic number 56. Barium is soft silvery metallic alkaline earth metal. It is never found in nature in its pure form due to its reactivity with air.Its oxide is historically known as baryta but it reacts with water and carbon dioxide and is not found as a mineral.de Araujo et al. 1986; Bazylinski et al. 2000,
