The zinc sulfate procuct is processed using phosphating process, jarosite process and goethite process to remove iron in it.
以炼铜烟灰制取硫酸锌产品，用磷酸盐法、黄钾铁矾法、针铁矿法对产品初步除铁，再用Ｈ２ Ｏ２ 氧化法对产品进行深度除铁，实验结果表明，采用针铁矿法，再配合Ｈ２ Ｏ２ 氧化法，除铁效果良好，酸浸液中铁含量可降至０－０１ ｇＬ 以下。
Compare to jarosite process, goethite process owns many advantages for the removeal of ferric or ferrous ions, such as large crystal, less valuable metal loss, filtration.
与湿法炼锌浸出溶液除铁方法——黄钾(钠)铁矾法相比,针铁矿法除铁具有除铁渣结晶体大,夹带有价金属少,容易过滤等优点,但针铁矿法除铁过程中必须加入针铁矿晶种,才能有效地除铁。
In this paper the properties of Chemical kinetics for reaction between goethite αFeOOH and chlorhydric acid HCI have been studied.
本文研究了针铁矿αFeOOH与盐酸反应的化学动力学特性,测定了它们的反应级数、速率常数、实验活化能和指(数)前因子。
