A Process Research on Aluminium Ammonium Sulfate from a Beryllium-metallurgic Plant

This paper presents a comprehensive utilization method of waste aluminium ammonium sulfate from commercial beryllium oxide using sulfuric-acid precipitation process. Recycling beryllium oxide from aluminium ammonium sulfate is washed by cold water,and Al2( SO4)3is prepared by adding Ca CO3,which could be used in defluorination processfrom high-fluorine beryllium ore,moreover,( NH4)2SO4could be used as additive in crystallization and aluminum removal process during industrial Be O production.
