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18409.5 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.Abstract: The paper introduces results of a comprehensive investigation on bauxite mines in all o -ver China .Statistical data concerning mining recovery , processing recovery , comprehensive recov-ery are analyzed.Bauxite occurs mainly as diaspore , total output of ores is 18409.5 kt.Large scale bauxite mines were accounting for 4 .09% in all in China and production capacity was ac-counting for 43 .30% .Ming recovery is 83 .91%, processing recovery 84 .99%, comprehensive recovery 75 .48%.3 .42% waste rock is reutilized , tailings from mineral processing remain tail-ings.
