The preparation of Ni-Zn ferrite from sodium jarosite residue was studied. 对黄钠铁矾渣制备复合镍锌铁氧体进行研究。
Obviously, jarosite process can successfully extract both zinc and indium. 可见，黄钾铁矾法工艺处理高铟锌精矿可以达到综合回收锌和铟的日的。
The compositions of oxidation film which could restrain biooxidation of arsenopyrite were indicated as jarosite and arsenolite by XRD. 用X射线粉晶衍射法对细菌氧化产物进行物相分析，结果表明氧化物的主要成分为黄钾铁矾，其次为砷华。
The leaching rate of zinc is up to 98.45%,and 95.08% indium deposited in jarosite residues can be effectively recovered. 生产实践表明采用该工艺,铟的总回收率可达72%25,锌的总回收率可达92%25。
Most iron can be removed through jarosite process.The content of zinc sulfate can reach more than 98% by evaporating, cooling, crystallization and centrifuging. 用黄铁矾法除去大部分铁,通过蒸发、冷却结晶、离心脱水,可最终使硫酸锌的含量达98%25以上。
This paper covers production practice of jarosite process in hot-acid leaching and comparison between iron hydroxide process and jarosite process that are used for iron removal. 介绍了热酸浸出黄钾铁矾工艺的生产实践，对氢氧化铁法和黄钾铁矾法两种除铁方法进行了比较。
