我国重要非金属矿产评价研究及重点勘查建议

Evaluation study on the important non-metallic minerals in China and suggestions for key exploration

非金属矿产在国民经济建设及战略性新兴产业中有重要应用。长期以来,我们侧重于重要矿产评价体系的研究,针对重要非金属矿产的研究较少。非金属矿产重要性评价对科学部署勘查规划具有重要的意义。本文首先界定了重要非金属矿产,根据重要非金属矿产定义选取了15个指标,构建了两套重要非金属矿产二维评价体系。一套是以供应风险和需求形势两个维度评价的大宗(战略新兴)紧缺矿产,另一套是以资源优势和市场优势两个维度评价的优势矿产。通过重要非金属矿产评价,对初步选取的20种非金属矿产进行评价,将石墨、萤石、叶蜡石、高纯石英原料(脉石英)、磷矿、滑石、钾盐、重晶石、硼矿、菱镁矿、硅灰石11种非金属矿产列为我国重要非金属矿产。对这11种重要非金属矿产勘查提出建议,为国家勘查部署提供参考。

Non-metallic mining industry is the foundation of national economy and has important application in national economic construction and strategic emerging industries.For a long time,we have focused on the study of important mineral resources evaluation system,but there are few studies on important mineral resources evaluation and less on important non-metallic minerals.The importance evaluation of non-metallic minerals is of great significance for scientific planning and guiding exploration deployment.By defining important non-metallic minerals and selecting 15 indicators,this paper constructs two sets of two-dimensional evaluation system for important non-metallic minerals.One is a large number of(strategic emerging)scarce minerals assessed from two dimensions of supply risk and demand situation,the other is superior mineral resources assessed from two dimensions of resource advantage and market advantage.Through the evaluation of important non-metallic minerals,20 kinds of non-metallic minerals were evaluated.11 kinds of non-metallic minerals including graphite,fluorite,pyrophyllite,high purity quartz raw material(vein quartz),phosphate rock,talc,potash,barite,boron,magnesium compounds and wollastonite were listed as important non-metallic minerals.Suggestions are put forward for the exploration of these 11 important non-metallic minerals,which can provide references for the national and commercial exploration deployment.
