摘要
对某铜矿的矿石、水、土壤作了系统取样。用INAA测定U、Th、K及其它微量元素含量,用天然放射性测Ra含量。发现铜矿石中有铀富集,且平衡系数偏镭,而生活区土壤偏铀,故提出妥善保管矿石以防止铀污染环境。因在矿石中有金及稀土含量富集,提出了综合利用资源的建议。
Samples of ore, water and soil in a copper deposit were collected. The contents of U, K, Th and other trace elements were determined by INAA, while Ra content was analysed by natural radioactivity survey. The results indicated uranium enrichment in the ores in contrast to in the soil around living area where equilibrium coefficient<1. So appropriate keeping of the copper ores was thought to be very important to protect the environment against pollution of radioactivity (uranium). Since gold and rare-earth elements enrichment in the ores were found, a suggestion of comprehensive utilizing the copper resources was put forward.
