| 摘 要： | 为了综合回收利用铜闪速熔炼烟灰，对铜闪速熔炼烟灰酸浸渣制备磁性材料进行了探索性研究.对熔炼烟灰酸浸渣进行了不同浓度盐酸浸出渣和除铅等工艺处理，研究了各工艺下浸出渣的磁性能.结果表明:杂质的去除有利于饱和磁化强度和剩磁的提高，但导致矫顽力下降.盐酸浸出处理的最佳性能出现在当盐酸浓度为3 mol/L时，饱和磁化强度和剩磁分别为10.965 A·m2/kg和0.964 A·m2/kg，矫顽力为3.33×103 A/m；除铅处理后浸出渣的磁化强度和剩磁分别达到11.065 A·m2/kg和0.94 A·m2/kg，矫顽力为3.228×103 A/m.

| Abstract: | Acid leaching slag of copper flash smelting dust preparation from magnetic materials was studied for the comprehensive use of copper flash smelting dust. Acid leaching slag of flash smelting dust was processed in different concentrations of hydrochloric acid and lead removal by analyzing the magnetic properties of different processes. The results show that saturation magnetization and remanence increases and coercivity decreases with removed impurities. The optimal acid leaching property occurs when the concentration of hydrochloric acid is 3 mol/L, the saturation magnetization and remanence are 10.965 A·m2/kg and 0.96374 A·m2/kg, and coercivity 3.33×103 A/m, respectively; acid leaching slag of lead removal, the saturation magnetization, remanence and coercivity are 11.065 A·m2/kg, 0.94 A·m2/kg and 3.228×103 A/m, respectively. |
