| Abstract: | Through pre-desilication of Al-Si minerals with NaOH solution,the amount of SiO2 and Al2O3 in slag were measured to calculate the ratio of Al203/SiO2.Impact of L/S ratio,digestion temperature and time,and alkali concentration etc on the ratio of Al2O3/SiO2 in the slag were investigated.The test showed that the ratio of Al2O3/SiO2 was from 0.89 up to 2.21 and silicon removal rate from mineral was up to 55% under the conditions of 40:1 L/S,95℃ temperature,180min digestion time,and 40% alkali concentration. |
