我国铜矿资源开发利用的技术经济评价

Technical and Economic Evaluation on Development and Utilization of China's Copper Resources

本文针对我国铜矿资源及其开发利用状况,建立了我国铜矿资源技术经济评价模型,并利用矿产资源技术经济评价软件系统,对我国铜矿资源进行了技术经济评价。评价结果表明,我国317个未利用铜矿区中有49个矿区的资源储量是经济的。最后,采用品位-吨位曲线表示了铜矿石品位和资源储量的关系,采用成本-吨位曲线表达了我国铜矿资源经济评价的结果。

According to China＇s copper resources and the circumstance of development and utilizaiton,this paper establishes the technical economic evaluation model on copper resources,and evaluates China＇s copper resources by the technical and economic evaluation software system of mineral resources. The evaluation results show that, there exists 49 mines of which resource reserves are economical in 317 undevelopment mines. Finally,it uses the curve of grade-tonnage to show the relationshio between grade and resource reserves of copper,and uses the curve of cost-tonnage to show the economic evaluation results on China＇s copper resources.
