摘　　要：含砷的有色金属和贵金属硫化矿在冶炼过程中会产生酸性高浓度含砷溶液,其具有砷浓度高、成分复杂、变化大、毒性强和难以存放等特点,如不加处理直接排放,会对环境和人类健康产生很大影响。综述了化学沉淀法、蒸发浓缩法和金属粉末法的脱砷原理及优缺点,以及各脱砷方法的研究进展,为脱砷技术发展提供参考和借鉴。Arsenic containing non-ferrous metal and precious metal sulfide ore will produce acidic high concentration arsenic solution in the smelting process,which has the characteristics of high arsenic concentration,complex composition,large changes,strong toxicity and difficult to store,such as direct discharge without treatment,will have a great impact on the environment and human health.In this paper,the principles,advantages and disadvantages of chemical precipitation method,evaporation enrichment method and metal powder method are reviewed,as well as the research progress of each method,so as to provide reference for the development of arsenic removal technology.
