Research Progress on Removing of Arsenic in Acidic High Concentration Arsenic Waste Solutions
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.
