本文作者提出了从碱式铝硅酸盐矿中制取氧化铝和碱的新方法。这个方法主要是燒结高碱生料,它与沃尔霍夫铝厂和皮卡列夫氧化铝厂采用的方法具有许多重大差异。现将这一新方法的实质介绍于下(图1)。原始的碱式铝硅酸盐矿与循环苛性碱液一起磨制,石灰石则与合碳酸碱(苏打和碳酸钾)的 The authors propose a new method for preparing alumina and alkali from basic aluminosilicates. This method, which is primarily sinter overbase, has many important differences from the methods used by the Volkhov Aluminum Plant and the Picarev Alumina Plant. Now the essence of this new method is introduced below (Figure 1). The original alkali aluminosilicate mills together with the circulating caustic liquor, and the limestone is ground with a mixture of sodium carbonate (soda and potassium carbonate)
