在玻璃和陶瓷工业中,霞石正长岩作为一种节能代碱替代长石的理想原料[1,2],主要引入SiO2、Al2O3、Na2O和K2O等有益组分,而铁和其它有色金属及其化合物则是有害组分,尤其是铁的含量直接影响玻陶制品的色泽和质量。我国大多数霞石正长岩矿产资源含铁量较高[3],其工业利用必须经过
In the glass and ceramics industry, nepheline syenite is an ideal raw material for energy-saving substitution of alkali for feldspar [1, 2], which mainly introduces beneficial components such as SiO2, Al2O3, Na2O and K2O, while iron and other non-ferrous metals And its compounds are harmful components, especially the content of iron directly affects the color and quality of pottery products. Most of China’s nepheline syenite mineral resources have a high iron content [3], its industrial use must go through
