非金属矿产和其他金属、可燃性有机岩、地下水等矿产资源一样,是进行四化建设的物质基础。随着现代科学技术发展和经济建设的需要,新的非金属矿产不断地发现并进入工业利用的领域,促使非金属矿产具有了较高的开发速度。因此,五十年代以来,世界非金属矿产不论在产量、产值和消费量上(指价值),均高于金属矿产一倍以上,改变了长期以来金 Non-metallic minerals and other metals, flammable organic rocks, groundwater and other mineral resources, is the material basis for the four modernizations. With the development of modern science and technology and the need of economic construction, new non-metallic minerals are continuously found in the fields of industrial utilization and have promoted the development of non-metallic minerals with high speed. Therefore, since the 1950s, the world’s non-metallic mineral resources are both more than doubled in output, output value and consumption (referring to value), which has changed the long-term gold
