炼铅顶吹炉氧化锌烟尘两段浸出的研究

Study on the two-stage leaching of zinc oxide dust from top-blowing lead smelting furnace

针对炼铅顶吹炉氧化锌烟尘所含杂质特点,采用两段浸出进行处理,控制不同的浸出条件回收铅锌,避免了杂质循环积累。

According to the characteristics of impurities contained in zinc oxide dust from top-blowing lead smelting furnace, two-stage leaching process is adopted for the treatment. Different leaching conditions are controlled to recover lead and zinc so as to avoid the cyclic accumulation of impurities.
