For highly pure barium sulphate to be produced barium sulfide is treated with sulfuric acid or salts. Barium carbonate is made commercially and in labs by treating barium sulfide with sodium carbonate using the soda ash method.

In the wild, barium elements are sulphate barite and less carbonate witherite. The sulfate is converted to chloride and in the electrolysis of melamine barium chloride produces barium metal.Barium compounds are notable for their high specific gravity which, in practical terms, means the compounds are extremely heavy. This is true of the most common barium-bearing mineral, its sulfate barite BaSO 4 is called heavy spar due to the high density 4.5 gcm 3 the size of a pea.
