补充资料：铝土矿
| 铝土矿 bauxite 以含水氧化铝为主、成分可变的天然多矿物混合物。主要由极细的三水铝石、软水铝石、硬水铝石和数量不等的粘土矿物、赤铁矿、针铁矿、石英等混合而成。含Al2O3量约40％～75％，是提炼铝的最主要矿石；也用来制取Al2O3，可作为磨料以及耐火材料。常呈豆状产出，但也呈块状、多孔状、土状等，随成因不同而异。颜色随氧化铁含量的增加，可呈白、灰直至棕红色，有时不同色彩呈斑点状分布。硬度和比重均较小，并随矿物组成不同而变化。铝土矿是由其母岩在湿热气候条件下经红土化作用而形成。由火成岩或变质岩形成的一般属红土型矿床，以三水铝石为主；由石灰岩或白云岩形成的，则属钙红土型，通常含有相当数量的软水铝石。风化壳铝土矿经剥蚀搬运，可形成沉积铝土矿。铝土矿分布广泛，法国的博奥是著名的重要产地；主要出产国有苏里南、牙买加、圭亚那等；中国广西、贵州、河南、山东等省也有广泛分布。 |
