摘要
介绍了我国铝土矿开采回采率、选矿回收率和综合利用率"三率"调查结果。我国铝土矿资源以一水硬铝石为主,年采出矿石量18 409.5 kt。大型矿山数量占全国总数的4.08%,采出矿石量占全国总量的45.30%。我国铝土矿资源开采回采率、选矿回收率、综合利用率分别为83.91%、84.99%、75.48%,全国铝土矿废石平均利用率3.42%,铝土矿选矿尾矿暂未规模化利用。
The paper introduces results of a comprehensive investigation on bauxite mines in all o-ver China. Statistical data concerning mining recovery, processing recovery, comprehensive recovery are analyzed. Bauxite occurs mainly as diaspore, total output of ores is 18 409. 5 kt. Large scale bauxite mines were accounting for 4. 0 9 % in all in China and production capacity was accounting for 43. 30% . Ming recovery is 83. 91 % , processing recovery 84. 9 9 % , comprehensive recovery 75.48%. 3. 42% waste rock is reutilized, tailings from mineral processing remain tailings.
