REFINING METHOD OF STEEL MAKING DUST SLURRY |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an adsorbent used for adsorbing a fluorine compound and especially used in order to rapidly and efficiently adsorb/insolubilize fluorine selectively even in the presence of various ions even if the concentration of the fluorine compound is low. <P>SOLUTION: In this refining method of the steel making dust slurry, the adsorbent composed of calcium oxide and calcium aluminate (Ca<SB>12</SB>Al<SB>14</SB>O<SB>33</SB>or the like) is used to a steel making dust slurry to adsorb and fix fluorine in the steel making dust slurry. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
