摘　　要：在重有色金属化学分析中,处理好化学分离问题,科学实现元素状态的分离,做好挥发处理工作,对分子进行蒸馏,运用沉淀法分离重有色金属,通过萃取进行分离,实现离子交换,根据不同色层予以分离,或者采用浮选分离法实现重有色金属化学分离,与此同时,应结合实际情况使用合适的分离技术特征,不断提升化学分离的实用性。In the chemical analysis of heavy non-ferrous metals,the problem of chemical separation should be dealt with scientifically.The separation of element states should be done scientifically,the volatilization work should be done well,the molecules should be distilled,the heavy non-ferrous metals can be separated by precipitation,and the separation can be achieved by extraction.Exchange,separate them according to different color layers,or use flotation separation to achieve chemical separation of heavy nonferrous metals.At the same time,appropriate separation technology characteristics should be used in combination with actual conditions to continuously improve the practicability of chemical separation.
