非金属矿工业是以矿产资源为基础的采掘工业。由于许多矿产品具有耐磨、耐高温、耐腐蚀、质轻、绝缘等优异的物理化学性能,因此世界各国对它的开发应用十分重视,已成为一个新掘起的重要的工业部门。1965年至1975年的十年中,世界非金属矿产品生产指数年平均增长率为金属的1.73倍,迄今仍保持这个增长的势头。美国年耗非金属矿物的价值,是年耗金属价值的两倍。我国非金属矿有着得天独厚的资源条件,种类齐全,品质优良,储量丰富。截至1983年底,全国已探明的非金属矿达74种,产地4700处,其中石膏储量居世界第一位,瓷土、石棉、石墨、滑石储量也占重要地位,大理石、花岗石著称于世,新
Non-metallic mining industry is based on mineral resources mining industry. Since many minerals have excellent physical and chemical properties such as wear resistance, high temperature resistance, corrosion resistance, light weight, and insulation, many countries in the world attach great importance to its development and application and have become a newly emerged important industrial sector. In the decade from 1965 to 1975, the annual growth rate of the world’s non-metallic mineral production index was an average of 1.73 times that of metal, and so far it has maintained its momentum of growth. The value of non-metallic minerals consumed by the United States is twice the value of annual consumption of metals. China’s non-metallic mineral resources have a unique situation, the full range, high quality, rich reserves. By the end of 1983, there were 74 nonmetallic minerals proven in the country, producing 4700 places, of which gypsum reserves ranked the first in the world, with clay, asbestos, graphite and talc reserves also occupying an important position. Marble and granite are famous in the world ,new
