摘要
介绍了我国硫铁矿开采回采率、选矿回收率和综合利用率"三率"调查结果。我国硫铁矿资源以黄铁矿为主,年采出矿石量8 443.4 kt。大型矿山数量占全国总数的5.00%,采出矿石量占全国总量的69.47%。我国硫铁矿资源开采回采率、选矿回收率、综合利用率分别为89.59%、83.93%、71.79%,我国硫铁矿尾矿利用率10.24%。
The paper introduces results of a comprehensive investigation on pyrites resources in all over China. Statistical data concerning mining recovery, processing recovery, comprehensive recovery are analyzed. Pyrites resources occurs mainly as pyrite, total output of ores is about 8 443.4 kt. Large scale pyrites mines were accounting for 5. 00 % in all in China and production capacity was accounting for 69. 47 % . Ming recovery of pyrites is 89. 59 % , processing recovery 83. 93 % , comprehensive recovery 71.79%. The utilization rate of tailings are 7.25 % .
