摘    要：介绍从海绵镉到精镉的一种清洁生产新工艺,阐述该工艺的技术特点:一是用氮气作为保护气体,实现粗镉、精镉的无氧浇铸;二是使用真空蒸馏技术,环保、低碳;三是收尘采用先进技术,烟尘排放量小于5 mg/m³。

Abstract: A new process to cleaner product refined cadmium from sponge cadmium was introduced with a detailed description of the features of the process.The first feature was to realize oxygen-free casting for crude and refined cadmium with nitrogen as the protection gas.The second one was to apply vacuum distillation technology which is low carbon and environmentally friendly.The third feature was to apply the advanced dust collection technology to ensure the dust emission is less than 5 mg/m³.
