随着工业发展和科学技术的进步,非金属矿物材料的应用领域越来越广,在国民经济发展中的地位大大提高。文中阐明了我国应重点发展的优势非金属矿产及其在世界贸易中的地位,指出了非金属矿物材料深加工技术需要改进和提高的研究方法和领域,应优先注重选矿提纯、超细粉碎、细粒分级及表面改性等技术的研究,重视与高新技术的结合应用,生产更多种类的非金属矿制品,向高增值化方向发展
With the development of industry and the progress of science and technology, the application field of non-metallic mineral materials is becoming more and more widespread, and its status in the development of national economy has been greatly enhanced. The article states the key non-metallic mineral resources to be developed in our country and its status in world trade. It points out the research methods and fields that need to be improved and improved in the deep-processing technology of non-metallic mineral materials, and priority should be given to the beneficiation, ultrafine grinding, fine Grading and surface modification of technology research, emphasis on the combination with high-tech applications, production of more types of non-metallic mineral products, to the direction of high value-added
