在锌冶炼过程中回收镉一般采用湿法,或湿法与火法联用,其缺点是流程长,加工费高。我厂采用密闭鼓风炉炼铅锌,烧结烟尘中镉未予回收,仍返回烧结。因此,原料中的镉大部份进入粗锌。在粗锌精炼过程中,镉以金属状态进入副产品高镉锌中。这种合金主要成份是锌和镉,其它杂质甚微,无工业用途。根 In the process of zinc smelting cadmium recovery generally used wet, or wet method and fire method, the disadvantage is the long process, high processing costs. I plant closed-end blast furnace lead-zinc, sinter dust in the cadmium was not recovered, still return to sintering. Therefore, most of the raw materials of cadmium into crude zinc. In the crude zinc refining process, cadmium enters the byproduct high-cadmium zinc as a metal. The main component of this alloy is zinc and cadmium, other impurities are minimal, no industrial use. root
