摘要
对四川和新疆5个矿山的膨润土进行了矿物组成和化学成分的测定,结合XRD、XRF分析确定了属性。采用11(O)为基础的计算方法对提纯后蒙脱石进行了晶体化学式计算;并根据层电荷的来源,对蒙脱石样品进行了属型划分。分析表明四川膨润土矿床样品属钙基膨润土,三台蒙脱石为切托-Otay型,盐亭蒙脱石为切托-Chambers型;新疆膨润土矿床样品属钠基膨润土,奇台蒙脱石为切托-Tatatilla型,吉木萨尔蒙脱石为怀俄明型。
The mineral composition and chemical composition of bentonite from Sichuan and Xinjiang was analyzed. The attribute of bentonite are fingered out according to the results of XRD and XRF. The crystal chemical formula of purified montmorillonite was calculated on the base of 11 （O）. The type of samples was identified according to the original of layer charge. The results showed that the samples from Sichuan are Ca- bentonite and the samples from Xinjiang are Na- bentonite. The type of montmorillonite from Santai, Yanting, Qitai, Jimusaer is Cheto-Otay-type, Cheto-Chambers-type, Cheto-TatatiUa, Wyoming-type respectly.
