摘要
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 。
Most bauxite in China is diasporic, and contains higher silica as well as alumina and with lower mass ratio of Al 2O 3/SiO 2.Commercial bauxite reserves with mass ratio of Al 2O 3/SiO 2 no less than 7 constitute 33% of A+B+C grade in proved bauxite reserves. As the fact that existing production technology of alumina from bauxite is not compatible with present situation of bauxite resources in China and increasingly losing its market competitiveness in the world of alumina, it is urgent that new technology and process be developed at present.
