【摘要】：对全国359座采矿权证磷矿山开发利用水平进行了调查评价。介绍了我国磷矿资源分布特点及其工业类型,统计分析了矿产开发利用"三率"(开采回采率、选矿回收率、综合利用率)指标及其影响因素等。结果表明,我国磷矿资源主要分布在南方地区,矿石类型以硅钙(镁)质磷块岩矿石、硅质磷块岩矿石、磷灰石(岩)矿石为主,年采出矿石量6 204.01万t。矿山数量以小型为主,占全国总量的58.33%,矿石开采以大中型矿山为主,采出矿石量占全国总量的77.59%。我国磷矿资源开采回采率、选矿回收率、综合利用率分别为82.70%、89.97%、77.79%;我国磷矿尾矿利用率16.77%,废石利用率1.22%。
[Abstract]:The level of exploitation and utilization of 359 mining right certificates of phosphate rock in China was investigated and evaluated. The distribution characteristics and industrial types of phosphate ore resources in China are introduced. The "three rates" (mining recovery rate, ore dressing recovery rate, comprehensive utilization ratio) and their influencing factors are statistically analyzed. The results show that the phosphate ore resources are mainly distributed in the south of China. The ore types are calcium silicate phosphate rock, siliceous phosphate rock and apatite. The annual output of phosphate ore is 62.0401 million tons. The number of mines is mainly small, accounting for 58.33% of the total amount of the whole country, the ore mining is mainly in large and medium-sized mines, and the amount of ore produced accounts for 77.59% of the total amount of the whole country. In China, the recovery rate, recovery rate and comprehensive utilization ratio of phosphate ore are 82.700.89.97 and 77.79, respectively, while the utilization ratio of phosphate tailings is 16.77g and the utilization ratio of waste rock is 1.22.
