The production of water-soluble barium salt from water and acid-insoluble barium sulfate as a raw material has not been carried out at all industrially0 [Problem to be solved by the invention] Since it does not dissolve, barium chloride and barium nitrate cannot be made directly. Therefore, when barium chromate is dissolved in sulfuric acid to obtain a chromic acid solution, there is no industrial method for regenerating the by-product barium sulfate into barium chromate. For example, barium sulfate does not react with sodium chromate, so it is necessary to convert it into a water-soluble barium salt for the reaction. Furthermore, in an attempt to produce barium carbonate, a water-soluble barium salt, when barium sulfate is boiled with a concentrated aqueous sodium carbonate solution, only a small portion undergoes double decomposition and does not change to 100% barium carbonate.

解し融塊状になる。The method for producing water-soluble barium salts from barium sulfate according to the present invention will be explained below using a chemical reaction formula. When sulfuric acid is applied to barium chromate, chromic acid and barium sulfate are produced. After collection, the barium sulfate precipitate is purified by filtering and washing with water to remove chromic acid. When anhydrous sodium carbonate is added to this and melted as in reaction (1), it metathesizes into barium carbonate and sodium sulfate, forming a molten lump.
