摘要
锌湿法冶炼中高钴锌精矿给生产带来一些麻烦,如中上清液含钴高及一次净化的除钴率低等.如果保持矿粉上清液含一定量的砷和锑,并控制合适的上清液温度,将有助于提高一次净化的除钴率;控制合适的温度和酸度,使部分系统钴开路,可避免钴的内部循环积累.
High-cobalt zinc concentrate bring some troubles in zinc hydrometallurgy, such as excess cobalt in middle-supernatant and low refine rate of first refine cobalt etc.. Refine rate of first refine cobalt can be increased if a amount of arsenic and antimony can be kept in middle-supernatant and appropriate temperature of middle-supernatant can be controlled. The accumulation of cobalt in intramural circulation can be restrained by controlling appropriate temperature and acidity, making open-circuit to part of cobalt.
