国外关键性矿产资源评价方法概述

关键性矿产资源对一个国家的国土安全、经济发展具有的意义。目前,国内并未发布关键性矿产的研究报告和结论。国外一些政府组织和研究机构对选定的金属和非金属矿产进行了关键性评价,制定了评价指标和评价方法,并且公布了的评价结果。但是这些研究的评价指标和评价方法并不一致,得到的关键性矿产的评价结果差异较大。本文通过对4个主要研究机构的研究报告进行分析概述,剖析关键性评估的理念、指标体系、评价方法和评价模型,比较不同研究的共同点及之间的差异。同时列举了国外主要研究机构建立的关键矿产目录,以便为我国的关键性矿产评价提供借鉴方法。

An overview of critical mineral resource assessments by foreign institutions

Critical mineral resource is of significant importance to the national security and economic development. Researches and conclusions about critical mineral resource are not published in China. Several government institution and working groups around the world have made criticality assessments for metallic and non-metallic mineral resource. Relevant indexes and methods are established and criticality of assessed mineral resource are ranked and published. However, the influence factors and methods on critical mineral resources assessment are variable and therefore the criticality assessments are heterogeneous. In this paper, 11 reports and articles from 4 different institutions are analysed. The critical concept, influences factors,methods and model during criticality assessment are summarized to compare the differences and similarities. And the critical mineral resource lists from these institutions are also shown to give a reference for critical mineral resource assessments in China.
