由于氧化铝生产的不断发展,扩大铝工业矿物基地的问题便显得更加突出。特别是要设法处理高硅铝矿、而要有效地利用高硅铝矿,则必须研制出有效的脱硅方法。在这方面最有前途的方法之一是微生物脱硅,即用微生物浸出铝硅酸盐。在硅酸盐分解时所有的微生物中,活性最大的叫做“硅酸盐”细菌的杆状粘液质细菌。这 Due to the continuous development of alumina production, the issue of expanding the aluminum industrial mineral base will become even more prominent. In particular, it is necessary to find ways to deal with high sialon, and to effectively utilize high sialite, it is necessary to develop an effective method for desilication. One of the most promising approaches in this regard is microbial desiliconization, which is the leaching of aluminosilicates with microorganisms. Of all the microorganisms that decompose silicate, the most active rod-shaped myxoid bacteria called “silicate” bacteria. This
