Total yearly world production estimated around 6,000,000 tons. Main mining locations are UK, Italy, Czech Republic, USA and Germany. Total world reserves approximated to be about 450,000,000 tons.Uses the Barium:Used in sparkplugs, vacuum tubes, fireworks, fluorescent lamps. Insoluble barium sulfate is supplied for human body imaging.Additional Notes:Must be stored under kerosene to stay pure. Soluble barium salt are very toxic.
