文中提出了一种以锂辉石为含锂原料生产含有微量 Li_2O 的氧化铝的方法。研究表明,经分解和氢氧化铝焙烧可制得含锂的氧化铝。以锂辉石为含锂原料生产含锂氧化铝,在技术方面是完全可行的。与采用纯碳酸锂作为添加剂相比,它在铝电解中将会取得更大的经济效益。
In this paper, a method for producing alumina with trace amount of Li 2 O using spodumene as a lithium-containing raw material is proposed. Studies have shown that after decomposition and calcination with aluminum hydroxide, lithium-containing alumina can be obtained. Spodumene lithium-containing raw materials to produce lithium-containing alumina, is technically feasible. Compared with the use of pure lithium carbonate as an additive, it will achieve greater economic benefits in aluminum electrolysis.
