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。
jarosite process can obtain high recovery rate of zinc, simultaneously, most of indium remains in the jarosite residues and a little part of indium remains in the high acidities leaching residues.
某锌精矿中铟含量很高,采用黄钾铁矾法处理该高铟锌精矿,在得到较高锌回收率的同时,大部分的铟进入矾渣,少部分进入高浸渣,从矾渣和高浸渣中可回收得到电铟。
the industrial tests show that the jarosite process can be used to handle the zinc calcine with high concentration of sb by controlling the leaching rate of sb in the neutral leaching process.
扩大试验验证,控制锑在中性浸出过程中的浸出率,黄钾铁矾法可以处理含锑高的锌焙烧料。
