摘要
介绍了我国铅矿开采回采率、选矿回收率和综合利用率"三率"调查结果。我国铅矿资源以以硫化铅锌矿石和混合铅锌矿为主,年采出矿石量8 946.7 kt。小型矿山数量占全国总量的96.67%,采出矿石量占全国总量的65.38%。我国铅矿资源开采回采率、选矿回收率、综合利用率分别为86.85%、84.69%、74.29%;我国铅矿尾矿利用率7.25%,废石利用率13.56%。
The paper introduces results of a comprehensive investigation on lead mines in all over China. Statistical data concerning mining recovery, processing recovery, comprehensive recovery are analyzed, lead ore occurs mainly as lead and zinc sulfide ores and sulfide - oxide mixed lead - zinc ore, total output of ores is 8 946. 7 kt. Small scale lead mines were accounting for 96. 67% in all in China and production capacity was accounting for 65. 38 % . Ming recovery is 86. 85 % , processing recovery 84. 69% , comprehensive recovery 74. 2 9 % . the utilization rate of tailings and waste rock were 1. 25% and 13.5 6 % .
