离子吸附型稀土资源研究进展、存在问题及今后研究方向

Progress, Problems and Research Orientation of Ion-adsorption Type Rare Earth Resources

  • 摘要: 稀土是中国的优势矿产资源,但真正引起世人瞩目的是离子吸附型稀土矿,尤其是其中的中稀土、重稀土成分。离子吸附型稀土矿是中国极其重要、全球罕见的矿床类型。自1969年发现至今的四十多年来,对其成矿机制、富集规律、开采方式、环境保护等方面的研究取得了显著进展。本文从离子吸附型稀土矿床成矿理论、勘查技术方法、资源综合利用及矿政管理等方面评述了近年来取得的进展及存在的问题,重点分析了合理评价资源储量、储量优化开采利用方案、加强稀土开发管理等方面存在的亟待解决的现实问题。本文认为现行的稀土矿产地质勘查规范已经不适应当前的形势,需要修改;当前对离子吸附型稀土矿产实行不分单元素矿种的资源分类方式也不利于资源的充分利用,需要建立单元素稀土矿种的评价、管理体系;对于矿业权设置和开采总量控制指标等方面的管理工作今后只能加强不能放松。

     

    Abstract: Rare earth is one of the superior mineral resources in China. But great attention has been focused on the ion-adsorption type rare earth resources, especially the medium and heavy rare earth. Ion-adsorption type rare earth ore is important resources in China, and extremely rare in the world. Since ion-adsorption type rare earth ore was discovered in 1962, outstanding progress has been achieved in the study on metallogenic mechanism, enrichment regularity, recovery method and environment protection for ion-adsorption type rare earth ore. This paper reviewed the progress in recent years and the existing problem in six aspects: metallogenic theory, exploration technique, comprehensive utilization of resources and mineral administration of ion-adsorption type rare earth ore. The urgent practical problems on reasonable evaluation of resources, optimizing the exploitation scheme and strengthening rare earth management & development are analyzed in details. It believes that the current geological exploration standard of rare earth mineral has unsuitable to the current situation, need to be modified. For ion-adsorption type rare earth ore, current resource classification method regardless of a single rare earth mineral is unfavorable to make full use of resources, need to establish a new evaluation and management system of a single rare earth mineral. In the future, management work for rare earth mining right setting and total mining control indicators should be strengthened.
