Abstract

PURPOSE:To easily separate and recover As and Sb by regulating a decoction contg. As and Sb obtd. by immersing a material contg. As, Sb, etc., into an alkali water soln. of prescribed pH and temp. to the specific pH, thereby precipitating Sb. CONSTITUTION:The material contg. As, Sb, S and other impurities is immersed into the alkali water soln. of >=10pH and 60-80 deg.C temp. Said As and Sb are then leached and the As concn. in the decoction is regulated to <=20g/l to separate the unreactant residue away. Acid is added to the decoction after the removal of said residue and the pH is regulated to 7-9.5, thereby precipitating and separating only Sb.
