Total yearly world production estimated approximately 6,000,000 tons. Key mining areas are UK, Italy, Czech Republic, USA and also Germany. Total people reserves estimated to be roughly 450,000,000 tons.Uses of Barium:Used in sparkplugs, vacuum tubes, fireworks, fluorescent lamps. Insoluble barium sulfate is offered for body imaging.Additional Notes:Must it is in stored under kerosene to stay pure. Soluble barium salt are highly toxic.
