摘要
稀土是发展高新技术不可缺少的资源,由于我国稀土资源过度开采,资源优势正逐步丧失,如何保护稀土矿种资源、促进稀土产业可持续发展是政府和学术界急待解决的问题。研究利用储采比关系式对主要稀土生产国以及中国主要稀土矿种的储采比进行了分析计算。在此基础上,利用储采比与开发时间关系预测模型,对我国主要稀土矿种的储采比进行了预测,到2020年,中国稀土资源总体储采比为233.44,其中混合型稀土矿、离子吸附型稀土矿和氟碳铈矿的储采比分别为535.01,37.11和109.78。该研究可作为选择稀土储备矿种的参考。
Rare earth is an indispensable resource in the development of high-tech industries. Because of over-exploitation, the advantage of rare earth resources in China has been gradually diminishing. Therefore, it is an urgent issue for the government and academia to protect the rare earth minerals resources and to promote the sustainable development of rare earth industry. Based on the relation of reserve-production ratio, the major producing countries of rare-earth and for the main rare earth minerals resources in China were calculated and analyzed. With prediction model between reserve-production ratio and development time, the prediction of the main rare earth minerals resources in China was carried out. By 2020, the total reserve-production ratio of rare-earth in China would be 233.44, in which the reserve-production ratio of mixed rare earth ores, ion-absorbed rare earth mineral resources and bastnasite mineral resources would be 535. 01, 37.1 and 109.78, respectively. The research results could be used as reference for selection of rare earth reserves in China
