氧化铝生产使用的是各种类型和质量不一的含铝原料。依据原料的矿物与化学组成的不同使用不同处理方法(拜耳法、烧结法、联合法)。所有处理方法的特点是耗费大量热能,因为必须通过高温水化学处理(铝土矿压煮溶 Alumina production uses a variety of different types and quality of aluminum-containing raw materials. Depending on the raw material of the mineral and chemical composition of the different use of different treatment methods (Bayer method, sintering method, the joint method). All treatment methods are characterized by a large amount of heat energy, as they must be chemically treated by high temperature water (bauxite boil
