| 摘 要： | 本文以贵州修文县的铝质岩为研究对象,分别对其做化学成分、矿物成分及镜下特征分析,分析结果表明:该铝质岩样中的主要化学成分为Al2O3、SiO2和Fe2O3,含量占80%左右;矿物成分主要为一水硬铝石、高岭石和赤铁矿;一水硬铝石主要以块状和粒状集合体为主,一水硬铝石颗粒间常被胶状含铁粘土或含有机质粘土充填、胶结;含硅矿物主要以高岭石的形式胶结在一水硬铝石表面;赤铁矿呈不透明黑色,主要以细-中粒状、细脉状胶结铝土矿产出。铝质岩的化学成分和矿物成分表明,铝质岩可应用于生产净水剂、高铝陶瓷及矿物聚合物等方面。

| Abstract: | Took the aluminum rock in Xiuwen Guizhou as main object.This experiment analyzed its chemical compositions,mineral compositions and microscopic characteristics respectively.The analysis results show that the main chemical compositions of the aluminum rock are Al2O3、SiO2and Fe2O3whose content is about 80%.The mineral compositions are mostly diasporite,kaolinite and hematite.The diasporite is mainly lumpy aggregate and granular aggregate.Intergranular of diasporite always filling with colloidal ferruginousclay and organic clay.The silicalite which is mainly in the shape of kaolinite glue on the surface of diasporite.Hematite is black and opaque.It always present in the shape of fine granular.The chemical and mineral composition show that the aluminum rock can be applied in water purifying agent,high alumina ceramics and geopolymer etc. |
