中国铝土矿资源的特点是多为一水硬铝石型，且高硅高铝，铝硅比在7以上的商品铝

土矿仅占现保有储量的33 ,，我国现行的氧化铝生产方法已愈益不适应目前的资源状况及日益竞争的国际市场，尽快发展研究适应我国铝土矿资源特点的新的氧化铝生产工艺方法是我国铝科技界的责任所在。-China' s bauxite resources are characterized more as a diaspore type, and high silicon aluminum, aluminum-silicon products than in more than 7 is to maintain reserves of bauxite accounted for only 33 , China' s current alumina production method has been increasingly unfit to present resource situation and the increasingly competitive international market, as soon as possible the development of China' s bauxite resources to adapt to the characteristics of a new alumina production process is China' s aluminum industry' s responsibility.
