【Abstract】 The precipitate of BaSO₄ can be obtained from the reaction of H₂SO₄ with BaCl₂ solution formed by the extraction of Ba-containing residue with HCl, the mother liquor is returned to the extraction process. The suitable conditions of the extraction are as follows:50min of extraction time, pH2-3,120 mesh of granularity of Ba-containing residue, 40-45℃ of extraction temperature and 3:1 of liquid-solid ratio.更多还原
