Analysis of the Rare Earth Mineral Resources Reserve System and Model Construction Based on Regional Development

Abstract

China is a large rare earth country that has pushed for related rare earth research, development, and application in the global development and progress of rare earths. The rare earth resource reserve strategy must be implemented by China due to the situation of rare earth resources at home and abroad, national security, and the need to strengthen the right to speak in the international market. This article builds the rare earth mineral resources reserve system and model from the perspective of regional development and uses the improved SURF algorithm to solve the problems of inaccurate mine location, mine location deviation, dislocation, overlap, and other issues, resulting in more accurate mineral resources reserve management data. The results show that the maximum relative error between the parallel profile method and the traditional method is 2.6%, which meets the requirement for mineral reserve calculation accuracy and can be used to calculate reserves. China’s peak ionic rare earth output will be 46,797.06 tonnes in 2024, and then, it will decline at a 4% annual rate thereafter. This demonstrates how a graded reserve and orderly promotion can improve the workflow and efficiency of the rare earth mineral resources reserve.

Predicting the Production and Depletion of Rare Earth Elements and Their Influence on Energy Sector Sustainability through the Utilization of Multilevel Linear Prediction Mixed-Effects Models with R Software

“…Future projections of rare earth production and reserves, both regionally and internationally, are crucial [30], as numerous studies advocate for the use of mathematical models as effective and versatile tools for analyzing forecasts, evaluating scenarios, and monitoring associated risks related to the depletion of these mineral resources. While notable examples of these models used are Gaussian, Gompertz, Weibull, Rayleigh, and log-normal, all of which have been employed in the fossil fuel sector, the results have been unsatisfactory, necessitating more flexible models [31].…”

"Individual Separation of Yttrium and Dysprosium Oxides from the Rare Earths Product obtained from Xenotime Mineral Concentrate"

“…In the non-nuclear sector, Y and Dy are used in the manufacture of super conductor, color television, ceramics, fluorescent lighting phosphors and computer displays [6-10]. In the nuclear sector, these two elements are used as control rods in nuclear reactors due to their relatively large neutron absorption cross section [11][12][13][14].…”

Application of Molecular Imprinting for Creation of Highly Selective Sorbents for Extraction and Separation of Rare-Earth Elements

“…There are new technologies and innovative products (and hence new demand), to which companies respond by modifying and reducing the cost of the production processes of their products. In this regard, an important aspect of the development of a national rare-earth industry is such institutional conditions for suppliers of rare-earth raw materials, its consumers and a state that would protect “their” enterprises and be able to address various crises and the destruction of existing global production chains [ 5 , 6 , 7 ].…”
