摘要
研究了膨润土活化酸浸新方法，实验结果表明，在适宜的活化剂存在下，膨润土酸浸速率有了显著的提高，铝的浸出率在９５％以上。酸浸渣经Ｘ－射线衍射和红外光谱分析表明，其主要成分为具有活性的二氧化硅。
In this paper,a new method of active acid leaching of bentonite is presented.The experimental results show that in the presence of some suitable active agents,the rate of acid leaching of bentonite is increased remarkably and the leaching ratio of aluminum in bentonite is greater than 95%.The acid leaching residue is studied by X ray diffraction analysis and IR spectrometry and the results show that it mainly consists of active silicon dioxide.
