摘要
膨润土矿在本省尚为缺门矿种。通过对省内钻井泥浆粘土矿的踏勘取样,经X射线衍射、红外光谱和差热等分析、测试手段及物化性能的测定,参照矿产工业要求,首次在贵州盘县地区被前人称为“绿豆岩”的岩层中,圈出了数个膨润土矿体;对矿石及矿石中小于2μm的粘粒矿物进行了物化性能及矿石、矿物的属性研究,确定区内膨润土矿为钙基和酸性钙基膨润土,其矿石中主要矿物——蒙脱石为钙质蒙脱石的属性;该膨润土矿不宜作钻井泥浆原料,但可为油脂脱色剂之用。该地区的膨润土矿有一定的工业价值和开发利用前景。
Bentonite ore is a rare ore in Guizhou Province, so the research work on it is very poor. Through analyses of samples, investigations of drilling-mud clay minerals, X-ray diffraction analyses, infrared spectral analyses and differential thermal analyses, etc.and after the testing and determining of the physicochemical properties and refering to the demand of mineral industry target, several Bentonite bodies have been circled in the rock strata once called 'mung bean rocks' by predecessors in Panxian County, Guizhou, and researches have been made of the physicochemical properties of the clay ores and the clay particle minerals smaller than two microns in the clay ores and of the properties of the ores and minerals. Bentonite ore in this area is deter-mined as calcium Bentonite and acidity calcium Bentonite whose mineral property belongs to calcium montmorillonite.
It is better for Bentonite ore not to be used as the raw material of drilling-mud, but it can be used as an oil decolourizer. Bentonite in this area has certain industry value and developing and utlizing prospects.
