| The Evaluation of China's Mineral Resources Demand and Exploration Priority Sequence |
| The choice of the most important minerals for exploration is of great guiding significance for the promotion of scientific deployment, improvement of the exploration work and alleviation of the pressure on resource supply effectively in the new period. In this paper the authors determined the priority sequence of mineral exploration on the basis of judging demand trends reasonably in the next 20 years. Firstly, 48 minerals were preliminarily screened out from 134 kinds of minerals for further evaluation by analyzing minerals’ supply and demand characteristics and establishing four principles. Secondly, the evaluation index system was established, which included 4 secondary indicators (resource insecurity, economic significance, defense and strategy significance, and exploration prospects) and 11 third-level indicators such as future demand trends. Then the importance ranking of 48 minerals was obtained with AHP. Lastly, some minerals were merged based on the consideration of the associated mineral resources, and then four-grade priority sequence for non-oil mineral exploration was determined: 1) Focused exploration minerals such as copper (cobalt) and uranium; 2) Priority exploration minerals such as Tin, graphite and fluorite; 3) Second priority exploration minerals such as silver, molybdenum and gold; 4) General exploration minerals such as diamond and pyrophyllite. |
