Abstract:With the increase of non-ferrous metallurgical output, a large number of arsenic containing waste residue, smoke and wastewater will be produced every year, which will not only cause great harm to the ecological environment, but also harm people's life and health. Therefore, it is necessary to treat them as resources and harmless. This paper reviews the process and principle of arsenic removal from arsenic containing waste materials in nonferrous metallurgical industry at home and abroad, mainly including pyrogenic process, hydro-process and combined process with pyrogenic process and hydro-process forarsenic removal. Among them, pyrogenic process arsenic removal is mainly in the form of As2O3 at high temperature; hydro-process arsenic removal is the leaching method that use acidic or alkaline medium usually to remove the arsenic in the form of arsenate. The problems in existing process and the new arsenic removal processes are discussed.
