摘　　要：研究并提出用稀盐酸、硼酸和反应助剂作为含有萤石、方解石杂质的重晶石粉体酸漂增白的新配方。新配方可以有效抑制氟化物对酸漂设备的腐蚀；生产的超微特级粉中的硫酸钡含量达９９％以上，产品白度（Ｒ４５７标）达９３。此种特级粉的各项技术指标均优于目前国内外同类粉体。The s study and bring forward a new formula for acid bleaching of barite powders containing impurities such as fluorite and calcite. The new formula is composed of dilute hydrochloride acid, boric acid and reaction assistant, and can efficiently restrain bleaching equipment from corrosion of fluoride. The content of barium sulfate in barite powders produced by the new process is over 99%, and its whiteness reaches 93. All technical indexes of the special grade powders are superior to the same categories at home and abroad.
