摘要
随着锌用途的扩大,低镉低铁锌出现市场需求。生产中,粗锌通过铅塔、镉塔的精馏精炼得到精锌产品。对铅塔、镉塔进行局部技术改造达到降低成品锌中镉、铁含量的目的,从而满足市场需求。
With zinc application expansion, low cadmium - iron zinc arises market demand. In the pro- duction, crude zinc is distillated and refined into zinc through lead tower and cadmium tower. By tech- nical transformating parts of lead tower and cadmium tower, cadmium and iron content in finished zinc is reduced. And product zinc meets market demand.
