| 中文摘要:玢岩型铁矿床是铁矿石的重要来源，其除了赋存巨量铁矿资源外，还以产出大量磷灰石为特征，伴生大量的磷、稀土、钒等资源。20世纪，矿业开发大多只回收主要矿种铁，对伴生资源的评价和综合利用较少。文章以凹山玢岩型铁矿田尾矿库为研究对象，开展伴生资源调查评价和综合利用示范研究。通过系统钻探采样、矿物组合分析、元素赋存状态和综合利用实验等研究，文章揭示出尾矿库中经济矿物为磷灰石，可综合利用资源为磷和稀土，并估算尾矿库中磷储量超过115万t、稀土5万t，社会和经济效益巨大，可作为范例进一步研究并推广应用。 |

| Abstract:The iron oxide-apatite deposit (IOA) is an important source of Fe ores, characterized by the abundant production of magnetite and apatite. Besides containing a huge amount of Fe ores, this type of deposit is also considerably associated with critical element ores, such as P, V, and REE. In the 20th century, most mining operations have only focused on the main minerals (Fe), with less utilization of associated resources in mineral deposits. In this study, systematic drilling sampling, mineral association study, element occurrence state analysis, and comprehensive utilization study have been performed on the Washan tailing pond at the Washan IOA ore field in eastern China. It is revealed that the primary resources that can be comprehensively utilized in the tailings pond are P and REE, and the main economic mineral is apatite. Preliminary calculations show that the reserves of P and REE in the Washan tailings pond exceed 1.15 million tons and 50000 tons, respectively, which has enormous social value potential and could be further studied and promoted as an example. |
