Baryte and celestine form a solid ...
Barium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of molten baryta (BaO). Barium is never found free in nature since it reacts with oxygen in the air, forming barium oxide (BaO), and with water, forming barium hydroxide (Ba(OH) 2) and hydrogen gas (H 2).Barium is most commonly found as the mineral barite (BaSO 4) and witherite (BaCO 3) and is ...

Barium is a soft alkaline earth metal belonging to Group IIA of the periodic table. Its silver-white colour changes to silver-yellow when it is exposed to air. It does not exist in nature in the elemental form but occurs as compounds with other elements (see Table 1). The principal
Barium is a divalent cation and alkaline earth metal that can be found in naturally occurring mineral deposits. The most common ores are found in Alaska, Arkansas, California, Georgia, Kentucky, Montana, Nevada, and Tennessee. In 2010, 670 thousand tons of barite, a natural barium sulfate ore, were mined in the US, most of it in Nevada.
