New Process of Harmless Resource Treatment of Arsenic Alkali Slag
Based on the characteristics of arsenic,antimony and alkali in arsenic-alkali slag,the alkali in arsenic-alkali slag is converted into sodium hydroxide,and then As-Antimony is volatilized by pyrotechnics,and the alkali,and inorganic dust such as silicon dioxide are separated by wet technoogy.The arsenic-containing fume produced by the process can be used as the raw material for extracting arsenic,the sodium hydroxide solution can be used for desulphurization of sulfur-containing fume,and the leaching slag can be used for building materials,which realizes the harmless and resource treatment of arsenic alkalislag.
