非金属矿是构成现代工业基础的三大矿产资源之一。由于它具有金属矿所没有的各种物理、化学特性,因此除了广泛应用于水泥、玻璃、陶瓷等建筑材料工业外,在国民经济的各行各业中也大量采用。随着工业的不断发展,非金属矿的生产迅速增长。据美国学者统计,世界非金属矿总产值:1950年为407亿美元,1960年为600亿美元;1970年999亿美元,1980年达1580亿美元。1945年以前,非金属矿产的开采值一直落后
Non-metallic mines are one of the three major mineral resources that form the basis of modern industry. Due to its various physical and chemical properties not found in metal mines, it has been extensively used in various industries in the national economy in addition to being widely used in building materials industries such as cement, glass and ceramics. With the continuous development of industry, the production of non-metallic ores has rapidly increased. According to statistics by American scholars, the output value of non-metallic minerals in the world is 40.7 billion U.S. dollars in 1950, 60 billion U.S. dollars in 1960, 99.9 billion U.S. dollars in 1970 and 158 billion U.S. dollars in 1980. Until 1945, the value of mining of non-metallic minerals has lagged behind
