摘要
老挝占巴色省巴松铝土矿经详查为一大型铝土矿床。该矿床位于占巴色省红土化作用强烈的波罗芬高原上,由玄武岩风化而成,属红土型三水铝土矿,Al2O3含量为28.63%～55.79%,Fe2O3含量为7.75%～52.30%,TiO2含量为1.06%～10.15%,铝硅比为2.6～48.5,具有中铝高铁、低硅低钛、高铝硅比的特点,矿体覆盖浅,地势平缓,适合大型机械化露天开采。
The auxite deposit in Pakxong Country, Champasak Province, Laos is a large deposit confirmed by the general explo- ration. The deposit is located in Boloven Plateau in Champasak Province, which is weathered from basalt and it is lateritic gibbsite, with Al2o3 content 28.63% -55.79% , Fe2O3 content 7.75% -52.30% ,TiO2 content 1.06% -10.15% , and the ratio of Al to Si 2.6 - 48.5. It has a characteristic of maddle Al, high Fe, Low Si, high ratio of Al to Si, occurring in the shallow and flat form and it is fit for large - scale mechanized opencast mining.
