摘要
以黄钾铁矾渣和硫酸锰为原料,通过热酸浸出、净化除杂、共沉淀和铁氧体工艺等过程,制备出锰锌铁氧体产品。实验结果表明,Fe和Zn的浸出率为90%～95%,Cu^(2+)、Cd^(2+)、Ca^(2+)和Mg^(2+)平均去除率分别为99%、85%、92%及85%;共沉淀粉含Fe 45.11%、Mn 16.12%、Zn 4.97%、Ca 0.0155%、Mg 0.0025%、Si 0.0017%、Cu 0.00058%、Cd 0.0006%;铁氧体产品的磁性能够达到日本TDK公司PC30指标。
The soft magnetic manganese-zinc ferrite was prepared by jarosite residues and manganese sulfate through hot-acid leaching, purification and impurity removal, co-precipitation, ferrite technology and so on. The test results showed that the leaching rates of Fe and Zn were 90%-95%, the average removal rates of Cu2＋, Cd2＋, Ca2＋ and Mg2＋ were 99%, 85%, 92% and 85%, respectively, and the co-precipitation powder contained 45.11% of Fe, 16.12% of Mn, 4.97% of Zn, 0.0155% of 0.0006% of Cd. The magnetism property of soft indicator of TDK Corporation in Japan. Ca, 0.0025% of Mg, 0.0017% of Si, 0.00058% of Cu, and magnetic manganese-zinc ferrite production reached PC30
