目前我国工业上利用的铝土矿,大都是原生沉积的层状铝土矿矿床。这种矿床,矿石的特点主要是高铝、高硅、低铁,铝硅比值较低。这就决定了生产氧化铝的方法只能采用与之相应的烧结法和串联联合法。近年来,我们根据冶金工业发展的需要,在广西某地探明了一个优质大型堆积型铝土矿矿床。经有关部门审查,认为质量好,规模 At present, most of the bauxite used industrially in our country are originally deposited layered bauxite deposits. This deposit, ore is characterized by high aluminum, high silicon, low iron, aluminum-silicon ratio is lower. This determines the production of alumina can only use the corresponding method of sintering and tandem method. In recent years, according to the needs of the development of metallurgical industry, we have proved a large-scale high-quality accumulation type bauxite deposit in Guangxi. After examination by the relevant departments, that the quality and scale
