摘要
为了提高铝土矿的品位，应用冶金反应工程观点，对山西铝土矿进行了预脱硅研究．实验结果表明，在焙烧温度９００～１１００℃、熔出温度９５℃、溶出用碱液含Ｎａ２Ｏ７７．５ｇ／Ｌ的条件下，铝硅比可由原矿的４．５，提高到精矿的１８左右．同时，对本文的实验结果和前人的研究结果进行了理论分析．
The study of desilication dealing with Shanxi bauxite using the method of metallurgical reaction engineering was performed. The result shows that when the roasting temperature is 900～1100℃, desilication temperature 95℃ and concetration of Na2O >77.5g/L, the A-S ratio is raised from 4. 5 for initial bauxite to 18 for concentrated ore obtained from the test.Theoretical analyses of our results and others' have been performed too.
