Abstract:
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 evaluation for metallic and non-metallic mineral resource.Relevant indexes and methods index are established and criticality of evaluation mineral resource are ranked and published.However,the evaluation index and methods on critical mineral resources evaluation are variable and therefore the criticality evaluation are heterogeneous.In this paper,11 reports and articles from 4 different institutions are analysed.The critical concept,evaluation index,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 evaluation in China.
