一水硬铝石型铝土矿全世界大多数已知铝土矿资源中都含有三水铝石成份;一水软铝石含量很少。一水硬铝石在几乎所有铝土矿中都存在,但一般是少量的。除了在印度库奇(kutch)半岛的某些小矿床探测到一水硬铝石局部富集外,红土化铝土矿床所含一水硬铝石不到0.5％。所有真正的 Diasporic Bauxite Most gypsum sources in the world contain gibbsite in most known bauxite resources; there is very little boehmite. Diaspore is present in almost all bauxite but is generally small. In addition to the localized enrichment of a diaspore at some small deposits in the kutch peninsula of India, the laterite bauxite contains less than 0.5% diaspore. All real
