战略性非金属矿产资源现状及加工技术研究进展OA

Strategic non-metallic minerals refer to non-metallic minerals that are crucial for high-quality economic development and national security.They play an important role in promoting the development of strategic emerging industries and supporting the realization of manufacturing country.The global reserves and productivity of four strate-gic non-metallic minerals listed in China are counted,and the resource situation and supply risk are judged.That is,phosphate ore and graphite are the dominant minerals in China;fluorite ore has changed from dominant minerals to scarce minerals;potassium salt is the scarce mineral in China,with a relatively high degree of external dependence.The progress of processing technology for four strategic non-metallic minerals from the aspects of new processes,new technologies,and new equipment are summarized,so as to provide reference for rational and efficient development of strategic non-metallic minerals and resource safety guarantee in China.
