Method for recovering valuable metals from steelmaking dust |
| abstract |
(57) [Abstract] [Purpose] To improve the efficiency of removing fluorine and chlorine in the method of recovering valuable metals from steelmaking dust containing zinc, iron, fluorine and chlorine and removing fluorine and chlorine. [Constitution] 350-5 after adding sulfuric acid to steelmaking dust and kneading Sulfate roasting is performed at 50 ° C. As the treatment of the sulfated roasting exhaust gas, washing with water; precipitation of a fluorine compound by neutralization of the washing water; filtration of the washing water after neutralization to transfer chlorine into the filtrate. |
