明矾石矿石和精矿同霞石矿石一样是重要的工业上惯用的原料,在氧化铝生产中将是铝土矿的有前途的代用品。根据铝土矿储量的消耗情况,明矾石的作用不但在苏联,而且在其他国家将会更大。在苏联有许多铝厂和生产氧化铝的工厂都以明矾石和霞石为基本原料。同时,在资本主义国家,类似的企业只用铝土矿为原料,有关非铝土矿原料生产氧化铝的问题至今还处于研 Alunite ores and concentrates, like nepheline ores, are important industrially customary raw materials and will be a promising substitute for bauxite in alumina production. According to the consumption of bauxite reserves, the role of alunite not only in the Soviet Union, but in other countries will be even greater. In the Soviet Union there are many aluminum mills and alumina production plants that use alundum and nephelite as their basic raw materials. In the meantime, in capitalist countries, similar enterprises use only bauxite as raw material, and the issue of alumina production from non-bauxite raw materials is still under study
