以一水硬铝石型铝土矿按拜耳法生产氧化铝时添加石灰对矿石溶出结果的影响,曾做过广泛的研究,但研究所用的矿石组成却各不相同,试验条件亦有差异。研究结果揭示出一个共同的特点:添加适量的石灰可以明显地改变矿石的溶出性能,获得最好的溶出率。而当石灰添加量超过某一限度时,由于生成含硅量不
Extensive studies have been conducted on the effects of adding lime on the digestion results of ore when producing diasporic bauxite by Bayer process, but the composition of the ore used in the study is varied and the test conditions varied. The findings reveal a common characteristic: the addition of an appropriate amount of lime can significantly alter the dissolution properties of the ore to obtain the best dissolution rate. When the amount of lime added exceeds a certain limit, the amount of silicon generated does not
