摘　　要：介绍了硫化砷渣资源化处理技术的现状。在冶金工业、化学工业等生产过程中,溶液脱砷处理常常采用硫化物沉淀法,从而产生硫化砷渣。砷化物既是剧毒物质,又是国民经济不可缺少的资源。由于历年开采,砷矿资源已经极有限。因此,从含砷废渣回收砷资源不仅是环境保护的需要,也是国民经济可持续发展的需要。The current situation of resource recovery technology of arsenic sulfide residues is introduced. The sulfide precipitation is used to remove arsenic from the solution in the process of metallurgical and chemical industry, with the arsenic sulfide residues produced. Arsenide is both hypertoxic and an indispensable resource for national economy, arsenic minerals resources are very limited for exploitation in past years, so the recovery of arsenic from arsenic sulfide residues is not only for environmental protection but also for national economy sustainable development.
