摘　　要：介绍了炼铝废渣综合利用的基础研究经验 :基于赤泥的化学组成 ,开创了用来生产水泥的先例 ;鉴于电解铝废阴极炭块业已石墨化、氟以NaF存在 ,发明了工业规模回收利用方法 ;依据固渣铝酸钙的热谱线 ,提出用作塑料阻燃剂 ,以及改性用作净水剂。In this paper, researches on multipurpos e utilization of slag from aluminium ind ustry are introduced. Based on its chemical composition, the slag was applied to produce cement initiatively. In view of graphitization of cathode mass and exis tence of F as NaF, the industrial scale recovery method for carbon block was inv ented. According to differential thermal curve, calcium aluminate in the slag ca n be used as plastics flame-retardant, or water treatment regent after modificat ion.
