随着湿法炼锌工业的日益发展,过去用回转窑处理锌浸出渣已经不能满足生产的需要。从国内几个大锌厂的生产情况来看,由于回转窑生产能力低,每年有30%的渣处理不了,造成渣的堆积,生产不平衡,资金不能周转,更重要的是,许多稀散金属得不到回收,给国家资源造成浪费。近几年来,尽 With the development of wet zinc smelting industry, the past use of rotary kiln zinc leaching residue can no longer meet the production needs. From the domestic production of several large zinc production point of view, due to the low productivity of rotary kiln, 30% of the slag can not handle each year, resulting in the accumulation of slag, production imbalance, the capital can not be revolving, more importantly, many of the scattered metal No recycling, resulting in waste of national resources. In recent years, do
