处理铜电解阳极泥有许多可行的方法。硒的状态和回收是处理阳极泥时特别关心的问题。关于阳极泥形成和特性的最新研究成果,将有助于对阳极泥处理所涉及的工艺化学的了解。最有前途的方法是对脱除铜和碲的阳极泥直接进行焙烧。在焙烧过程中,硒以二氧化硒的形式挥发,铅等杂质变为炉渣,于是便得到高质量的多尔合金。 There are many possible ways to deal with copper electrolytic anode slime. Selenium status and recovery are of particular concern when dealing with anode slime. Recent research on the formation and characterization of anode slimes will help to understand the process chemistry involved in anode slime treatment. The most promising method is to directly roast the anode slime removing copper and tellurium. In the roasting process, selenium is volatilized in the form of selenium dioxide, impurities such as lead are converted into slag, and high-quality Dole alloy is obtained.
