The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。
