低品位硬岩铀矿床开采技术状况与发展方向

Mining technical progress and development direction of low grade hard rock uranium deposit

我国硬岩铀矿一般品位低,采矿贫化率与损失率较大,目前成本高,经济效益不好,传统的铀矿开采技术面临挑战。从低品位硬岩铀矿床开采技术与发展方向进行分析论述,探讨提高低品位硬岩铀矿床开采技术的措施与途径。

The hard rock uranium ore in China generally has low grade with large dilution rate of min- ing and loss ratio , high cost and poor economic efficiency at present. The traditional mining technique of uranium ore is exposed to challenge. From two aspects of currently low grade of hard rock uranium deposit mining technique and development direction are expatiated. Improving of measures and ways of low hard rock uranium deposit mining technique is discussed.
