当前,世界上大部分的锌来自电解厂,电解法越来越多地使用含铁较高的矿石。这些矿的含铁最可达到15%。因此,电解法炼锌,必须采用有效或便宜的处理浸出渣的方法。近年来出现了两种主要方法,即“黄钾铁矾”和“针铁矿”法。本文所介绍的是黄钾铁矾法。黄钾铁矾法在西班牙已应用十几年之久,现在世界上约有十几个工厂应用此法。这两种新方法开始由阿纳康达铜矿公司的米舍尔于 Currently, most of the world’s zinc comes from electrolysis plants, and the electrolysis uses more and more iron ore. Iron ore in these mines can reach up to 15%. Therefore, electrolytic zinc smelting, we must use an effective or cheap leaching residue method. In recent years there have been two main approaches, namely “jarosite” and “goethite” method. This article describes the jarosite method. The jarosite method has been used in Spain for more than a decade, and now there are about a dozen factories in the world applying this method. Both of these new methods began with Mitac in Anaconda Copper Company
