我国铝土矿高铝、高硅、低铁的特点,决定了烧结法氧化铝生产工艺在我国有着非常重要的地位,特别是随着高品位铝土矿的日益匮乏,烧结法处理低品位铝土矿的优越性日益凸显出来。而烧结法存在生产工艺流程复杂、工艺能耗高等不利因素,尤其是湿法系统的结垢问题, China’s bauxite high-alumina, high-silicon, low-iron characteristics, determines the sintering process alumina production technology in our country has a very important position, especially with the growing lack of high-grade bauxite, sinter treatment of low-grade aluminum The superiority of earth mines has become increasingly prominent. The sintering method exists in the production process is complex, high energy consumption and other unfavorable factors, especially the scaling of the wet system,
